What variable, value or condition do I check to check the existence of "ThisForm.OtherForm"? I want to make sure the new form is closed before it is called again, because the form creates a cursor to populate the data, and the initial cursor would be destroyed thus causing a problem when returning to the first open instance. Is there a conditional statement to test before issuing ThisForm.OtherForm.Release() ?

This could also be applied when closing the first form as well (if I follow your discussion with Naomi).

Thanks,

dg
