NK1 Iterate Logic

Hello!  I’m working on some code that should only send NK1;1-3 if NK1;3 = M and NK1;2.1 != null.  On the ADT coming into Cloverleaf the NK1 has multiple repeating segments but the receiving system only wants the NK1 segment for the Mother.  I have a segment Iterate on NK1 as follows:

Action:  Iterate

Type:  segment

Basis: 0(0).NK1

Variable: %n1

The code is as follows:  

 IF  0(0).NK1(%n1).#3(0).[0] eq =M &&  0(0).NK1(%n1).#2(0).[0] ne @null

 Copy:  0(0).NK1(%n1).#1(0).[0]->0(0).NK1(0).#1(0).[0]

 Copy:  0(0).NK1(%n1).#2(0).[0]->0(0).NK1(0).#2(0).[0]

           0(0).NK1(%n1).#2(0).[1]->0(0).NK1(0).#2(0).[1]

 Copy:  0(0).NK1(%n1).#3(0).[0]->0(0).NK1(0).#3(0).[0]

This is the NK1 data as it is coming inbound to CL:

NK1|1|Asdf^Asdfasdf|F||(562)543-2132||EMC

NK1|2|Asdfasdf^Asdfasdf|M|6545 What^^Signal Hill^CA^90806|(562)652-1300||NOK||||||NO EMPLOYER|||20090505

In this example, we only want the 2nd iteration of the NK1 to be mapped in the outbound ADT but currently, both iterations are being sent.  Any suggestions are greatly appreciated.

Best Regards,
