Bonus TIPS for Successful Posting

Try a Search First
It is highly recommended that a Search be done on your topic before posting, as many questions have been answered in prior posts. As with any search engine, the shorter the search term, the more "hits" will be returned, but the more specific the search term is, the greater the relevance of those "hits". Searching for "table" might well return every message on the board while "tablesum" would greatly restrict the number of messages returned.

When you do post
First, make sure you are posting your question in the correct forum. For example, if you post an issue regarding Desktop applications on the Mobile & Browser Applications board , not only will your question not be seen by the appropriate audience, it may also be removed or relocated.

The more detail you provide about your problem or question, the more likely someone is to understand your request and be able to help. A sample database with a minimum of records (and its support files, zipped together) will make it much easier to diagnose issues with your application. Screen shots of error messages are especially helpful.

When explaining how to reproduce your problem, please be as detailed as possible. Describe every step, click-by-click and keypress-by-keypress. Otherwise when others try to duplicate your problem, they may do something slightly different and end up with different results.

A note about attachments
You may only attach one file to each message. Attachment file size is limited to 2MB. If you need to include several files, you may do so by zipping them into a single archive.

If you forgot to attach your files to your post, please do NOT create a new thread. Instead, reply to your original message and attach the file there.

When attaching screen shots, it is best to attach an image file (.BMP, .JPG, .GIF, .PNG, etc.) or a zip file of several images, as opposed to a Word document containing the screen shots. Because Word documents are prone to viruses, many message board users will not open your Word file, therefore limiting their ability to help you.

Similarly, if you are uploading a zipped archive, you should simply create a .ZIP file and not a self-extracting .EXE as many users will not run your EXE file.

"count" on records

  • "count" on records

    I realize this has to be the easiest problem to solve, but for some reason I am drawing a blank.

    I have a report that list several fields. I want to count (quantity) the number of times each field appears on the report.

    Ex:

    Total Records = 64
    Doors (appears on record) = 10
    Windows (appears on record) = 5
    Etc…

    When I use Count( doors ), the result is 64…same with all the fields.

    Re: "count" on records

    Sorry for the confusion -

    Should have read:

    Total Records = 64
    Doors (appears on report) = 10 times
    Windows (appears on report) = 5 times
    Etc…

      Hi Brent,

      Not quite sure what value you are looking for, for Doors.

      The number of times doors are within the 64 records? ie 1-64.

      Or the total number of doors for all 64 records?

      Have you tried to drag the field you want the Count of to the footer and selected Count from the dialog box?

        Keith,

        Actually, wanting the number of times "Doors" appears on the report. I have 30-35 in the record, only 10 on the report.

          Brent, I share Keith's confusion.

          Is "doors" a separate field in each record of your table? If not, is it a field value that appears in some records but not others? What is the name of the field that might contain this value? Is the field value the character string "DOORS" or something else?

          We have no way to know what you mean when you say

          "Doors" appears on the report?

          Try describing it to us as you would to a blind man. After all we can't see your database, your table, your report, and have no context in which to try to interpret what you've written.

            Brent,

            Does that mean you have 30-35 records with a value greater that 0 in the report of 64 records?

              Re: "count" on records

              Sorry for the confusion:

              I have a table that contains a field “Doors”. Within this table, some of the records have information entered into “Doors”, some do not.

              I have a report that contains the field “Doors”, which list 10 times on the report the information contained in the table.

              I want to create a Count for the number of times this information appears on this report. When I use the Count() function Count (Doors), I get the total amount of records stored within the table.

                Much better.

                Permit me to rephrase in alphaspeak...

                You want a count of the number of RECORDS that appear in your report that CONTAIN a NON BLANK value in the DOORS field of each RECORD.

                A good approach to this takes two steps.

                a) create a new calculated field in your report layout. Define an expression that will return 1 if the DOORS field is not blank or that will return a 0 if the DOORS field is blank. Something like this should work:
                Code:
                IF(is_blank("Doors"),0,1)
                b) drag that new calc field into the report footer and tell the genie to TOTAL it across all the records in the report. The effect is to add all the zeros and ones together, toget a count.

                Make sense?

                  Tom,

                  Thank you for your help. I tried entering the function you suggested, and I get an "Invalid or incomplete expression".

                  I even copied and pasted your function - same result.

                    Hi Brent,

                    If you can post a small sample of your application you will be surprised at the result.

                      Re: "count" on records

                      IF(isblank("Doors"),0,1)

                      I did say "something like this"... :)

                      I suppose I imagined you might crack open the help file and look for information on the is_blank function. You would have seen that I mistyped it including an unnecessary underscore.

                      Tip: when you get help from the message board that involves new functions or expressions take a couple of minutes, with the help file open beside you, to figure out why and how the suggested expression works (or doesn't). It's how one climbs the Alpha Five learning curve.

                      Good luck with your project.

                        I have searched through the Alpha Help and cannot figure out what I’m doing wrong. The attached should help in explaining my problem.

                        The total for door is accounting for the blank record.

                        Please help!!!

                          Pictures of the output are pretty but don't reveal what expressions you are using.

                            Stan,

                            door_count expression “count(Door)”
                            window_count expression “count(Windows)”


                            The Door & Window are character fields.

                              And why are you using those expressions when it has already been explained to you that you need to

                              create a calculated field

                              door_count = IF(isblank("Door"),0,1)

                              create anther calculated field

                              window_count = IF(isblank("Windows"),0,1)

                              Then drag each in turn into the footer where you want the count to appear and when the genie appears, specify TOTAL.
                              There can be only one.
