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.

    Total() function in a form???

    I'm trying to create a calculated field in a form to add up all of a students class hours based on an ID number. The form I created have has an embedded browse that shows all the students classes and hours. How can I create a field to add up all the hours ONLY for the student/ID Number who has focus???

    I've tried to use the Total() function but its giving me the total for the entire table, my problem is getting it to only count the hours for the ID that has focus. Please Help!

    Hi Ivan,

    You can create view to handle that in the database side and use that in the component.
    Here is something similar I did and re-use that all over the No Interest Loan Application.

    Code:
    SELECT       
        LoansFK, SUM(VoucherAmount) AS TotalDisbursedAmount
    FROM
        dbo.Vouchers
    GROUP BY LoansFK, Status
    HAVING  (Status = 'Printed')
    You can have code like that to create the actual view:
    Code:
    CREATE VIEW [dbo].[vStudentsTrans]
    AS
    SELECT       
        StudentPK, SUM(Hours) AS TotalHours
    FROM
        dbo.Students
    GROUP BY StudentPK
    My view had more calculations and the benefit is that the back end calculations is always faster from the front end.
    You can use just a grid and then use the Detail View to show each student record in details.

          Ok,

          Check the Invoice form in the AlphaSports sample database that ships with Alpha Five. The "Total" calc field on that form will be of interest, I think.

            Most use tablesum() or dbsum() anywhere such a total is needed (outside a report).
            There can be only one.

                Re: Total() function in a form???

                Im currently using this:

                TABLESUM("courses.DBF", "ssn = '" + ssn + "' ", "Completed_hrs")

                Which is working perfectly for adding up all the hours a student has, however, is there a way I can make it not count the completed hours for a specified class such as class "ABL"? I have multiple classes that I would like it to ignore the count on, is there an expression for that or do I need to rethink my table structure?

                    however I'm getting <invalid or incomplete expression>

                      Additionally, I'm trying to use/come up with a way to have it add all the hours a student has, while excluding certain classes and also making sure that it does not count duplicate classes (a class that a student has taken repeatedly).

                      I really need to find something to sharpen my knowledge when it comes to writing expessions,

                      Thanks in advance for all your help.

                        looking at that - ABL should be within quotes

                        TABLESUM("courses.DBF", "ssn = '" + ssn + "' " + ".AND. Class<>'ABL'".... should work

                          Which can be compressed to

                          TABLESUM("courses.DBF", "ssn = '" + ssn + "' .AND. Class<>'ABL'", "Completed_hrs")
                          There can be only one.

                            So I typed this and all works fine:

                            TABLESUM("courses.dbf", "ssn=' "+ssn+" ' .and. Course_Name<>'Mandatory Orientation' ", "Completed_hrs")

                            but I need to exclude about four courses, so wrote the following:

                            TABLESUM("courses.DBF", "(ssn = '" + ssn + "') .and. (Course_name<>'Mandatory Orientation' .or. Course_Name<>'Sponsored Mandatory Orientation' .or. Course_Name<>'Sponsored Mandatory Orientation (lcm)' .or. Course_Name<>'Sponsored Mandatory Orientation (lif)') ", "Completed_hrs")

                            and this expression does not produce the result I would like, Im checking a student that only has the Course "Mandatory Orientation" and when I use the first expression above his hours come out to zero which is correct. But when I use the second expression above, his hours come out to 40 which is not what im looking for.

                            What am I doing wrong?

                              TABLESUM("courses.DBF", "ssn = '" + ssn + "' .and. Course_name<>'Mandatory Orientation' .and. Course_Name<>'Sponsored Mandatory Orientation' .and. Course_Name<>'Sponsored Mandatory Orientation (lcm)' .and. Course_Name<>'Sponsored Mandatory Orientation (lif)' ", "Completed_hrs")

                              or

                              TABLESUM("courses.DBF", "ssn = '" + ssn + "' .and. Course_name != 'Mandatory Orientation' .and. Course_Name != 'Sponsored Mandatory Orientation' .and. Course_Name != 'Sponsored Mandatory Orientation (lcm)' .and. Course_Name != 'Sponsored Mandatory Orientation (lif)' ", "Completed_hrs")

                              or, guessing here

                              TABLESUM("courses.DBF", "ssn = '" + ssn + "' .and. ('Mandatory' !$ Course_Name)", "Completed_hrs")
