>I agree the global object reference would work, but it seems it would also be kind of tricky to keep track of multiple instances of the form. I was hoping there was some way to have a reference of the form in the filter statement. I think this would satisfy the eval statement of the filter in the cusPushPopRecNo destroy method. I just don't know what the reference should be.

There can be, but it can't be a relative reference like thisform, because thisform can revaluate independently of the cursor. The form has an object instance associated with it, and if you insist on using a form property for a filter, you'd best make certain that it resolves consistently. And this is very tough to do using this or thisform...
