On Error GoTo errh
    SplitStringToSeprator = "Split Error"

    If Len(oSeparator) > 1 Then
        SplitStringToSeprator = "Invalid separator"
        Exit Function
    End If
    Dim insrter As String
    If Len(oString) > oBrokenLength Then
        Dim i As Long
        Dim totalLength As Long
        totalLength = Len(oString)
        For i = 1 To totalLength
            Dim oValTrim As String
            If insrter <> Empty Then
                insrter = insrter & oSeparator
            End If
            If Len(oString) > oBrokenLength Then
                oValTrim = Left(oString, oBrokenLength)
                If insrter <> Empty Then
                    insrter = insrter & oValTrim
                Else
                    insrter = oValTrim
                End If
                oString = Replace(oString, oValTrim, "")
            Else
                insrter = insrter & oString
            End If
            i = i + oBrokenLength
        Next i
