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.

    Calculated Fields on Subform

    What changes are necessary to expressions for calculated fields that are used on subforms in order for them to work? In the attached database, all the calculated fields that work so well on the form when it is used by itself display the name of the field in the corresponding type-in text boxes, instead of the calculation result.

    I'm also having problems with checkmarks disappearing on the FIRST new record entered on the subform. After this record is saved, the checkmarks stay put. To see this in action, open the "FormwithSubform" form and click the APC checkbox. Now click on the WTR checkbox or the NWR checkbox. The checkmark in APC disappears! Save the record and try it again on the next record. It doesn't happen again. It also doesn't happen when using the Subform by itself.

    At Ken Nordin's suggestion (from another thread), I have extensively experimented with adding and removing the checkboxes, but the disappearing checkmark continues to be a problem.

    Please help!

    Charlain:

    I don't know why you need the sub form. You already had all the calculation going on in the servicetest table.

    See the attached. I made some changes a got rid of a bunch of extra child records that had no links. That a look.

      Hi Bob,
      Thanks for the help. I'll take a look at your file. I should've mentioned in my first post that this is just a watered down version of my actual form & subform -- I only put the fields in this test version that were giving me so many problems!

      I appreciate the help!

        Hi Bob,

        Just took a look, and I see you removed the subform. Problem is, I really need to figure out how to make these calculations work on a subform. Once I know how to do it on this watered-down form, I can get it to work on my real form & subform. Thanks anyway for your help, and if you have any more ideas, I'd really appreciate hearing them.

            Charlain,

            Unzip the attachment to an empty folder.

            I found that the subform works ok if the calc field expressions in the form used as the subform are modified slightly. Modifications consist of including explicit references to the tablename for each field mentioned in a calc field expression.
