Can anyone tell me why the following function to test the uniqueness o
values in a (single and same) range fails to fire? It's based on th
Worksheet Array formula *=MAX(COUNTIF(rng,rng)) *returning 1 fo
"unique", otherwise "not unique".

Function UniqueTest(rng1 As Range, rng2 As Range) As String

Application.Volatile

x = Application.Evaluate("Max(Countif(rng1,rng2))")
If x = 1 Then
UniqueTest = "Unique"
Else
UniqueTest = "Not Unique"
End If

End Function


and neither does ...

Function UniqueTest2(rng1 As Range, rng2 As Range) As String

Application.Volatile

x = [Max(Countif(rng1,rng2))]
If x = 1 Then
UniqueTest2 = "Unique"
Else
UniqueTest2 = "Not Unique"
End If

End Function

TIA

Myle
