>the new property to a form in a formset, and it went onto the formset instead. Also I am getting the error message, "Unknown member Lastcontrol..." The new property shows up and is set to .F., but I must not be setting it up right. I need another pointer if possible.

If you referencing in the form's activate event you can just reference it as
thisform.lastcontrol

From another form in the formset you would need to reference
thisformset.formwhatever.lastcontrol

Make sure you have made it a property of the form and not of the formset.
