Remove the parentheses that are around the argument list in the call to
the subs.
(or you use Call).

My vote goes to "Call", I find that easier to read and maintain (but I know
I'm in the minority):

Sub alterSheet()
Call Hide_Cells (Range("C22:L28"))
End Sub

Sub alterSheet2()
Call Reveal_Cells (3,Range("C21:L28"))
End Sub

Best wishes Harald
