Blank Form When Filtering

[forms_are_nightmares]

I checked the forum and couldn't find a specific reference to this problem.

I have a form (with a few subforms) and some combo boxes at the top for filtering. Everything works fine with one exception. If a user selects criteria in the combo boxes and hits the filter button the form goes blank, i.e., no data satisfies the criteria.

Problem: The user has to exit the database because all the fields, boxes...etc. are gone.

How can I prevent the form from going blank?

thanks.
