Color Code Tweak

I am using the following code to change colors in set of autoshapes (Thanks Colin_L and Norie) and it works fine for the first autoshape but has it has no effect on the subsequent autoshapes. I plan on using the code for about 200 autoshapes, I thought I could just copy the first code and keep adding it on for each autoshape... I am guessing that the code is stopping after the first set and not continuing?



Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$C$46" Then

'Change autoshape color to red depending upon cell value, or blank of no value is entered.
With ActiveSheet.Shapes("Rectangle 1").Fill.ForeColor
If Target.Value = "" Then
.SchemeColor = 1
ElseIf Target.Value >= 422 Then
.SchemeColor = 50
ElseIf Target.Value >= 1 Then
.SchemeColor = 10
Else
'it must be less than 1
End If
End With
End If......
