Pathcopy iterate question

Here is my inbound ORC segment:

ORC|NW|1012^OrderID~1012^OccOrder_ID~1818^Order_ID|

I have a pathcopy on the ORC segment, but I need to iterate through the 2nd field, look for Order_ID, and put that number in the outbound ORC.2

This is what I have:

IF                2(0).0(0).ORC.00216(%f1).[1] eq =Order_ID

  COPY        2(0).0(0).ORC.00216(%f1).[0] -> 1(0).0(0).ORC.00216(0).[0]

Expected Outcome:

ORC|NW|1818|

Actual Outcome:

ORC|NW|1818^OrderID~1012^OccOrder_ID~1818^Order_ID|

I’m sure I am missing something, but I can’t figure out what it is.  Any help would be greatly appreciated.
