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.

    complex lookup table

    In one of my forms, I have the customer name field and a contact field that corresponds to that company. The user will use a drop down box of customers to select one and then I would like to be able to have the contact field drop down box contain only contacts from the company that was selected. However, the twist is that in the table for this form, there are 4 contact fields (so a max of 4 contacts can be entered for a company) and I need it to do the lookup in all 4 fields to create the drop down list. I think my problem lies in that the contact lookup table in the field rules is set up wrong, but I'm not sure how to do what I need to do. Any help would be greatly appreciated.

    Pat,

    It sounds like what you want is the Cascading List lookup. Use the A5 Online Help, search on 'lookup' and navigate to Cascading List to see the explanation of the logic and an example.

      RE: complex lookup table

      Thanks, Dave. Actually after looking through that section about cascading lookups, I think a table lookup with a filter might work. The only problem is that it says to create a session variable for the one field (in my case it would be the customer name), but I don't know how to fill in the chart for defining a variable. I opened the appropriate table, went to Table, Global Variables, and then the chart opens for defining variables. I'm not sure what name and value to enter for my variable. Have you used this before?

        Pat,

        If you have a Customer table which has 4 fields for contacts it may be simpler to have a separate table for contacts linked as a 1 to many set. In doing this you can use the customer table to look up the customer and the contact table as a table lookup filtered on the customer name.

        I believe your "twist" may be your problem.

        If you only wish to select a single contact for each entry then you need to select from contact records and not contact fields.

        I trust you understand my ramblings ????

          Perhaps if you post the shell of the DB you're trying to fix?

          Bo

          Would it be possible to gather all the contact info into one table and then have a filterred query return the 4 related sub selects???
