I'm using excel 2007.
As a note the link was here.

I might as well post the code,, but I just couldn't get it to work, shame, because it sounds like it could be what I was after, I'll post it now, but if anyone can help me with this that would be great


Sub CompareWorksheetRanges(rng1 As Range, rng2 As Range)
Dim r As Long, c As Integer
Dim lr1 As Long, lr2 As Long, lc1 As Integer, lc2 As Integer
Dim maxR As Long, maxC As Integer, cf1 As String, cf2 As String
Dim rptWB As Workbook, DiffCount As Long
If rng1 Is Nothing Or rng2 Is Nothing Then Exit Sub
If rng1.Areas.Count > 1 Or rng2.Areas.Count > 1 Then
MsgBox "Can't compare multiple selections!", _
vbExclamation, "Compare Worksheet Ranges"
Exit Sub
