This section of the forum is intended for reporting possible software bugs. If you post questions like these in the FM Pro Forum (See tab at top of this screen), your question will be seen and responded to by many more fellow users.
Normally, I'd simply go ahead and answer your question here, but you haven't really posted enough detail for anyone to help you. I suggest that you repost this question in the FM Pro Forum and provide much more detail about your database and what you want to do.
Please read this link. Please DO NOT post replies directly to it.
