>>I have a grid displaying information on MIS calls. One of the fields on the grid refers to a Computer information table to get the computer name. The call file uses the computer's asset tag number as the key to perform the relation on. The grid displays fine when first displayed but when I perform a filter on the call file and then go top the computer names disapear. I have double checked everything and all seems setup ok.

Thanks Jess
Your suggestion got me to the problem. The relation does not change but the form I use to define the filter uses combo boxes to display choices. One of these boxes displayes information from the file that the grid is related to. When I list this file it messes up the relation back at the grid. I found it by creating a test button that just puts a manual filter on the grid. This worked fine - so the problem had to be the filter form - and therefore the combo box. I will try a private data session for the filter form to fix it.

Thanks again
