I have tried what I think you describe and it seems to work OK. I don't understand what you say about "Each sheet has a User form..." because the user forms are not linked to sheets, and I don't understand what you mean by "...call another User Form..." - is this just showing the form by using form.open in a vba subroutine? How does the first form open? Are the forms modal or non-modal? When one form opens another does the code in the form close itself or does it stay open? Post some code, that would help
