Dim cl As Range, cUnique As New Collection, i As Long, uList() As Variant
On Error Resume Next
For Each cl In InputRange
If cl.Formula <> "" Then
cUnique.Add cl.Value, CStr(cl.Value)
End If
Next cl
UniqueItemList = ""
If cUnique.Count > 0 Then
ReDim uList(1 To cUnique.Count)
For i = 1 To cUnique.Count
