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.

    My DBSUM() Not Working Properly

    I created a field in the Invoice_Header table, Dbsum_Inv_Itms. I made it a calculated field with this expression..

    DBSUM("invoice items","Invoice_Id","Invoice_Id","Extn")

    The expression builder shows it as N with a value of 0 no matter which record I check it with. Same result using the Interactive window.

    invoice_items = table
    invoice_id = index
    invoice_id = Key_Value is defined as "An explicit value or the name of a field in the table containing the value. I presume this needs to be the common linking field which is 'invoice_id'.
    Extn = A valid numeric expression or a numeric field from the lookup table.

    Extn is a calculated field in the invoice_items table which is simply Quantity*Retail.

    I also tried this expression and end up with the same results.

    DBSUM("invoice items","Invoice_Id","Invoice_Id","Quantity*Retail")

    I've attached a zip file

    Thanks,

    Hi Kenn,

    The key needs to evaluate to a value of the key, not a string.

    DBSUM("invoice items","Invoice_Id","Invoice_Id","Extn")
    the 3rd parameter "Invoice_Id" is a key value looking for the string "Invoice_Id" in the key, which will never exist. You want the value of the current recor's Invoice ID, so the expression should be

    DBSUM("invoice items","Invoice_Id",Invoice_Id,"Extn")

      Hi Ira,

      How did you ever pull yourself away from the game to answer this? Anyhow, your correction works well.

      There's crying time in eagletown tonight. 3 out of 4 and last 2 in a row. Can't argue with that.

      Thanks for the help.
