I have entered the following and the row will not change to default
color when $A(whatever) is not equal to "Weekly Subtotal". It does
change to orange when "Weekly Subtotal" is entered into a cell but wont
change back to excel default color if cell is changed back to "". What
am i doing wrong!

Private Sub Workbook_Open()
Dim cell As Range, rng As Range
Dim Sh As Worksheet
For Each Sh In ThisWorkbook.Worksheets
For Each cell In Sh.Range("AL6:AL2000")
If cell.Value = "Weekly Subtotal" Then
Set rng = Intersect(Sh.Range("A8:J2000"), _
cell.EntireRow)
rng.Interior.ColorIndex = 45
If cell.Value = "" Then
Set rng = Intersect(Sh.Range("A8:J2000"), _
cell.EntireRow)
rng.Interior.ColorIndex = xlNone
End If
End If
Next
Next

End Sub
