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.

    Nested IF statement or.......

    I need a calculated field to show anywhere from 1 to 8 positive responses. I created logical fields and then wrote a calculated field with nested if statements such as: if(X'.t.,"yes",if(y=.t.,"yes","") etc. Written in the normal way, the nested if statement will only show 1 of several possibilities. In this situation, I need it to show anywhere from 1 to 8 posibilities.

    Do I need to rethink my approach to the fields? How do I write a nested statement to show all positive posibilities?

    Thanks,

    Hi Ken
    Check out using a CASE statement. Works a little easier than using multiple if statements. I personally use them quite a bit.

        Ken,

        give us an example of what 3 positive responses might look like. Then give us an example of what 5 would look like.

          The CASE statement still only returns a single result such as: CASE(TEMP80, "Really Hot")

          Here's my expression and it could return 1 or all values:

          CASE(Mfipcashl=.t.,"MFIP-Cash", Mfipfoodl=.t.,"MFIP-Food", Mal=.t.,"MA", Gamcl=.t.,"GAMC", Eal=.t.,"EA")

          In this case there are 3 positives and it returned the first positive. It needs to return all 3.

          Thanks,

            Your best approach is to write a custom function. For example:

            function ken as c(mfipcashl as l, mfipfoodl as l,
            mal as l. gamcl as l, eal as l)
            dim temp as c
            temp=""
            crlf=chr(13)+chr(10)

            if mfipcashl=.t. then
            temp=temp+"MFIP-Cash"+crlf
            end if
            if mfipfoodl=.t. then
            temp=temp+"MFIP-FOOD"+crlf
            end if
            if Mal=.t. then
            temp=temp+"MA"+crlf
            end if
            if Gamcl=.t. then
            temp=temp+"GAMC"+crlf
            end if
            if Eal=.t. then
            temp=temp+"EA"
            end if
            ken=temp
            end function

            Then you make your calculated field into
            ken(mfipcashl, mfipfoodl, mal, gamcl, eal)

              It looks like you might need to add ranges to the decision formula using .AND. & .OR.

              temp>32.AND.temp65.AND.temp80.AND.temp

                Peter,

                Thank you for your input. This is my first attempt in this area, creating a custom letter. There's always a learning experience in A5.

                I appreciate your suggestion.

                  Ken,

                  Assuming there is enough room in the expression line,

                  IF(X,"x is yes; ","")+IF(Y,"y is yes; ","")+IF(Z,"z is yes; ","")+...

                  Note that if X is a logical value, then the following are the same, but the 2nd is shorter.

                  IF(X=.t.,"x is yes; ","")
                  IF(X,"x is yes; ","")
