Hi

Would anyone know how to pass the reference of one CCK object to another CCK object during object creation as an argument?
(cck = content creation kit)

Ex:
If i have two cck content types A and B with the following fields.

A ( aid, some field)
B (bid, aid, somefiled)

so that every B is related to an A.

When creating a new B object, how can I a pass the reference of an existing A object (ie an 'aid') via an argument (through the URL)? [ this should happen without the user having to enter it manuall -- i.e when the user clicks  a particular URL  a chosen aid shuold be passed ]

Tnx in advance

Srimal.
