Break down string by delimiter and concatanate with another broken down cell

I need help Completing a VBA UDF that will take a string in a certain format, and return it in a different one.
I have to "assisting" UDFs for that.. This is what I have so far:
Function STR_SPLIT(str, sep, n) As String 'Splits String by delimiter and return array in n position
    Dim V() As String
    V = Split(str, sep)
    STR_SPLIT = V(n - 1)
End Function

Function COUNTTEXT(ref_value As Range, ref_string As String) As Integer 'Counts how many times a certain character appears in a given cell

Dim i As Integer, count As Integer

count = 0
If Len(ref_string) <> 1 Then COUNTTEXT = CVErr(xlErrValue): Exit Function
For i = 1 To Len(ref_value.Value)
    If Mid(ref_value, i, 1) = ref_string Then count = count + 1


End Function

Function LDAPFORM(SourceOU As Range, SourceFQDN As Range) As String
    'First we need to check if the original Cell is empty.
    If IsEmpty(SourceOU) Then
        LDAPFORM = ""
        Exit Function
    End If
    'If the SourceOU is not empty, we will need to count how many times the "\" character appears to make the right Result String
    Dim cnt As Integer
    cnt = COUNTTEXT(SourceOU, "\")
    Dim i As Integer
    For i = 0 To cnt
End Function

Open in new window

Basically I have Two cells,
One is called Source OU That has several Strings seperated by "\" For exmple : IL\Administration\Junior
and another Called SourchFQDN that should have some sort of FQDN for example: mydom.local

What I need my UDF to do is to take these two cells and return it in a valid LDAP format, in this case:
The OU should be returned in reverse order.
Please see attached File for example (File is Macro-enabled!)

You may try something like this...

Function OUCN(ByVal OU As String, ByVal FQDN As String) As String
Dim arrOU() As String, arrFQDN() As String
Dim i As Long
Dim str As String
arrOU = Split(OU, "\")
For i = UBound(arrOU) To 0 Step -1
    If LCase(arrOU(i)) Like "[a-z]*" Then
        If str = "" Then
            str = "OU=" & arrOU(i)
            str = str & "," & "OU=" & arrOU(i)
        End If
    End If
Next i
arrFQDN = Split(FQDN, ".")
For i = 0 To UBound(arrFQDN)
    str = str & "," & "DC=" & arrFQDN(i)
Next i
OUCN = str
End Function

Open in new window

In the attached, the function is placed on Module2 and the formula is placed in column D.

Is that what you are trying to achieve?
