Thanks everyone for helping. Not sure how to attach the excel file. If there is a way please let me know

here is the code in the VB components that I have. I can see that you produced a component on the fly and tested it, which is something I can test as well. But if you want add my custom made function to your excel file as well and test as well

Function Concat2(myRange As Range, Optional myDelimiter As String)
    Dim r As Range

    Application.Volatile
    For Each r In myRange
        If Len(r.Text) > 0 Then
            Concat2 = Concat2 & r & myDelimiter
        End If
    Next r
    If Len(myDelimiter) > 0 Then
        Concat2 = Left(Concat2, Len(Concat2) - Len(myDelimiter))
    End If
End Function

One thing that I just noticed which might be causing problem is Application.volatile. Let me search a bit on that to see if it is causing problems.Thanks very much for your assistance again
