Hi R#
I am not sure I follow.
in my ChildForm when I declare formMainReference : TMainForm it does not know
what TMainForm is since unit2 has no idea about unit1 (MainForm). Can you give
me the details of what unit1(MainForm) and unit2(ChildForm) looks like since I
cannot get it to work. Thanks.
Best,
