Suppose I have a value in A1 and the formula
=FormatCell(A1), calling the following macro, in B1

Function FormatCell(a As Range)
a.Cells(1, 1).Select
Selection.Font.Bold = True
Selection.Font.ColorIndex = 3
End Function

Why I hav'nt A1 formatted?
I have breakpointed the macro and it triggers when I change the A1
value.
