Excel: TranslateChar(StrIn as string) as string doesn't work for me

Dear experts,

In excel im trying to get this function from Matthewspatrick to work. If it works i think this is exactly what i would like to have! I am using excel 2010
 

Function TranslateChar(StrIn As String) As String
     
     ' This function may be used in Excel or Access, or in any VB/VBA project.
     
     ' Function evaluates an ANSI string that may have special characters, identified
     ' in the collection populated below.  If a special character is found, the function
     ' replaces that character with a designated replacement string (may be any number
     ' of characters).  There is no support for Unicode.
     
     ' The function conserves case, so if the special character is uppercase, then the
     ' first character of the replacement string will be uppercase as well.
     
     ' While the intent of this function is to "replace" characters with diacritical
     ' marks with their Roman alphabet equivalents (you should feel free to change the
     ' mapping below if you do not think it's right or it does not suit your purposes;
     ' I am no linguist).  However, you could use the code to replace any single ANSI
     ' character with whatever string you desire.
     
    Dim Counter As Long
    Dim coll As New Collection
    Dim Check As String
    Dim WasLower As Boolean
    Dim Letter As String
     
     ' See if the collection exists.  The collection is set up as a static variable, so
     ' that it will persist between function calls; that will save a few cycles on later
     ' function calls as there will be no need to create and populate the collection again.
     ' There wil be no "Set coll = Nothing" to release the object variable, though; we
     ' will rely on VBA to clean up the collection object for us when the user exits the
     ' application
     
If coll Is Nothing Then


         
       ' Set coll = New collection

        coll.Add Item:="A", Key:="À"
        coll.Add Item:="a", Key:="à"
        coll.Add Item:="A", Key:="Á"

        coll.Add Item:="I", Key:="Ï"
        coll.Add Item:="i", Key:="ï"

        coll.Add Item:="O", Key:="Ò"
        coll.Add Item:="o", Key:="ò"

        coll.Add Item:="O", Key:="Ô"
        coll.Add Item:="o", Key:="ô"
        coll.Add Item:="O", Key:="Õ"
        coll.Add Item:="o", Key:="õ"
        coll.Add Item:="O", Key:="Ö"
        coll.Add Item:="o", Key:="ö"
        coll.Add Item:="O", Key:="Ø"
        coll.Add Item:="o", Key:="ø"
        coll.Add Item:="U", Key:="Ù"

        coll.Add Item:="U", Key:="Ü"
        coll.Add Item:="u", Key:="ü"
End If

     
     ' Loop through string to look for special characters needing replacement
     
    For Counter = 1 To Len(StrIn)
         
         ' Look in collection to see if the current character being considered is a "special"
         ' character
         
        On Error Resume Next
        Letter = Mid(StrIn, Counter, 1)
        Check = coll(Letter)
         
         ' Check to see if original character was upper or lower case
         
        WasLower = (StrComp(Letter, LCase(Letter), vbBinaryCompare) = 0)
        
         
         ' If there was no error, that means character was in collection and thus is a
         ' special character needing replacement
         
        If Err <> 0 Then
            Err.Clear
            Check = Letter
            
        End If
        On Error GoTo 0
         
         ' If character was lower case, return the translation in lower case.  If upper case,
         ' return in proper case (first character capitalized)
         
        TranslateChar = TranslateChar & IIf(WasLower, LCase(Check), StrConv(Check, vbProperCase))
    Next

End Function

Select allOpen in new window

I have put the function into a cell like: TranslateChar(D1)
in D1 there is a string like Øvre Røssaga and i want to get Ovre Rossaga.

I hope someone can help me,

Cheers,
