This one I do know! I have fallen for the same trap many times.
Me["somename"] returns an object that "looks" like a Control, but it's
not its an Object, which doesn't have a "Text" property.
You do have to assign it to a Control (or a specific control type) in
order to get the properties expected.
Dim hLbl As Label
hLbl=Me["label" & $iIndex]
BTW It is wonderful that this is so! As it enables us to write hundreds
of custom controls which may have any number of weird properties unknown
to Me[controlname As String]
I will amend the help.
