Cetin,

Yes I tested the code (and thank you for the time you put into it) but I kept getting a 'function error' on running it. What I've done since then is dropped the parent relationship and for the moment am just trying to retrieve, from one table, the latest (in date order) referral record for any MNO as per the example. Once I have that sorted we can go back to working on the parent/child model

Hope you are well - do you actually live in Turkey by the way?
