Kiza,

No need for a macro. In Cell C1, use the formula

=IF(ISERROR(MATCH(A1,B:B,FALSE)),"In Column A, but not in Column B","")

And copy down to match your data in column A.

Hi,

I have two columns, A and B, which both contain numerical information.
Column A is the master column with the correct information in. Column B
is a copy of Column A however, not all of the information from Column A
is in Column B. I am therefore trying to identifiy which items of
numerical information is in Column A but not Column B.

I have a macro which will loop through but there is one line in there
which I do not know how to change in order for it to identify which
items of numerical information are not in Column B.

The two columns do not match up in terms of size so I cannot sort them
and offset the macro. I am looking at a cell in Column A to be matched
up with a cell in Column B which I believe needs to be a range.

I have pasted the code below and if any one could assist me, I would
appreciate it.

Sub Cell_Colour()
'
Dim rwIndex, ColIndex
'
For ColIndex = 1 To 2 ' ColIndex means Columns 1 To 2
rwIndex = 2 ' rwIndex means maco starts from Row 2
'
Sheets("Sheet2").Select
Do Until Range("A" & rwIndex) = ""
Cells(rwIndex, ColIndex).Select
'
If Cells(rwIndex, ColIndex).Value = Cells(rwIndex - 1, ColIndex).Value
Then
Selection.Interior.ColorIndex = 35
End If
rwIndex = rwIndex + 1
Loop
ColIndex = ColIndex + 1
Next ColIndex
End Sub

The line which I am having problems with is:
If Cells(rwIndex, ColIndex).Value = Cells(rwIndex - 1, ColIndex).Value
Then

Perhaps Column B needs to be named but this is where I am struggling.

Any help would be appreciated.
Kiza
