I need to resize select columns and rows whenever A1="Resize".
Columns and rows are hidden and the sheet is password protected
(password="sparrow"). When A1="Resize", I need the hidden row and
column headers to appear so another macro I have will adjust select
column and row widths and heights. When finished, I need to delete
the A1 "Resize" entry and the headers to once again be hidden and
protected.

Following is the resize macro but it currently does not affect
headers:

Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = Range("A1").Address Then
Columns("C:C").ColumnWidth = Range("A1").Value
End If
If Target.Address = Range("A2").Address Then
Rows("3:3").RowHeight = Range("A2").Value
End If
End Sub

Thanks for any help that can be given.
