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.

    Problem searching records using variables

    I have two variable record list combo fields on a form. The first combo is filled with product names the second combo is filled with colors. The product is selected frst and then the color is seclcted. the second field has an on change event which opens a report with the filtered expression: Product_Used=var->productlookup .AND. Color=var->color The report opens with no data.

    Hi Gary,

    The filter is working. Have you tested the value of your variables?

      Re: Problem searching records using variables

      Keith's idea is a good one. Use constants (literals) to build the filter expression, and then substitute the variables into the expression only after it's working ok.

      It's possible, the product_used and color values in your lookups probably have already been trimmed of trailing blanks. This would mean that your variables would not have trailing blanks while your field values would include trailing blanks. The comparison may be failing because the two strings are not equal. One has trailing blanks the other does not, if you see what I meahn. I wonder if you need to compared trimmed field values with the variables... ? i.e.

      Code:
      trim(Product_Used) = var->productlookup .AND. trim(Color) = var->color
      It's not clear to me where the filter is being specified. If it's in the properties of the report layout itself, then the scope of the variables used in the filter expression needs to be GLOBAL

      If these ideas don't get you where you need to go, zip a copy of the database and attach to a reply in this thread. Tell us how to find and trigger the fault.

        Make sure these variables are GLOBAL.
