>Actually I thought I got it but I am still having the problem. I narrowed it down that it only happens when I try seeking on this specific table. this table seems to be the same as all the other ones. DO you have any other ideas?

Shevy,
As said before I suspect from a define in form's include file or some property that has 'thisformset' in it, not the table or index itself.

Just before seek() I'd put these to check :

Activate screen
? '.Value',.Value
? 'Alias', "AliasAsIsInSeekExpression"
? 'Tag', "TagAsIsInSeekExpression"
