HI, even with the typo corrrected - I am still getting the error.

Here is the corrected code, and I am still getting the error.

Function FReplace1(ReplaceField1) As String


If
Application.WorksheetFunction.IsNumber(Application .WorksheetFunction.Search("/", ReplaceField1)) = "true" Then
ReplaceField1 = Replace(ReplaceField1, "/", "_")
FReplace1 = ReplaceField1

Else

FReplace1 = ReplaceField1
End If

End Function

FFeplace1 = ReplaceField1
There is a typo in this line: Type FReplace1 instead of FFeplace1
