I would like to add the cell contents delimited by ","
v(i) = (individual program #'s) to row 27 so that we can fiind the
duplicates individually instead of seeing which cells has dupes, I could see
which program # is a dupe. I can't seem to be able to set the cell row
reference to see where I have the with and end with to break out the ?
thanks,

Sub CkforDupes()

Dim rng As Range, cell As Range
Dim i As Long, c1 As Long
Dim v
Dim rowcounter As Integer
Set rng = Range("D1", Range("D65536").End(xlUp))

For Each cell In rng
v = MACSplit(cell.Text, ",")

For i = LBound(v) To UBound(v)
c1 = Application.CountIf(rng, "*" & v(i) & "*")
If c1 1 Then ' it should be 1 to match itself
MsgBox v(i) & " :possible dups"


cell.Interior.ColorIndex = 3
End If
Debug.Print "v(i): ("; i; ")"; v(i)
Next
rowcounter = rowcounter + 1
