My code is shown below. I have two questions - When I protect my sheet, it
no longer allows the cells to be color filled based on the value, any way to
allow this to happen? Right now only column A is color coded. I would like
columns B and C to be filled with the same color as A1, A2, A3, etc. based on
the value entered in column A. Any suggestions? Your help is greatly
appreciated. Thanks.

Private Sub Worksheet_Change(ByVal Target As Range)
Const WS_RANGE As String = "A3:A322"

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
With Target
Select Case .Value
Case 1: .Interior.ColorIndex = 44
