Hi,
I have the following function that is called everytime a worksheet is
changed, I would like to only allow the function to run on certain
worksheets because I have code on other sheets and having this
function called makes it really slow, so is there a way to specify
which sheets can call the function ?

Thanks in advance

**FUNCTION**
Option Base 1
Function UniqueItems(ArrayIn, Optional Count As Variant) As Variant
Dim Unique() As Variant
Dim u() As Variant
Dim Element As Variant
Dim i As Integer
Dim FoundMatch As Boolean
Dim r As Range
Set r = Application.Caller
If IsMissing(Count) Then Count = True
NumUnique = 0
For Each Element In ArrayIn
FoundMatch = False
For i = 1 To NumUnique
If Element = Unique(i) Or Element = 0 Then
FoundMatch = True
GoTo AddItem
End If
Next i
AddItem:
If Not FoundMatch Then
NumUnique = NumUnique + 1
ReDim Preserve Unique(NumUnique)
Unique(NumUnique) = Element
End If
Next Element
If Count Then
UniqueItems = NumUnique
Else
If NumUnique r.Count Then
ReDim Preserve Unique(1 To r.Count)
Unique(UBound(Unique)) = (NumUnique - r.Count) + 1 & " more"
UniqueItems = Application.Transpose(Unique)
ElseIf NumUnique < r.Count Then
ReDim Preserve Unique(1 To r.Count)
For i = NumUnique + 1 To r.Count
Unique(i) = ""
Next
UniqueItems = Application.Transpose(Unique)
Else
UniqueItems = Application.Transpose(Unique)
End If
End If
End Function
