Interesting idea.
I do this all the time with VB6, but I can't seem to get this
to work  in Excel.

I have a command button on Sheet1 named cbSTART.
I created a form and changed these properties manually:
-- (Name) -> FormTest
-- Caption -> FormTest
-- BackColor -> Light green

How do I get the form to appear? This is what I tried...

Sub cbSTART_Click()
-- FormTest.Top=500
-- FormTest.Visible = True <<---------- crashes here
End Sub
