That worked! Funny how the Page balks at the RemoveObject(). I am not totally happy with the Form holding the container bec. it then remains on screen when the user goes to another page. Would there be a good way to trigger the RemoveObject code (which is in the Close commandbutton) if the user moved to the other page? I tried to put it in the container's LostFocus like this:

THIS.Parent.cmdClose.Click()

but it crashed just as before.

Thanks again for your help.
