DBMultirecord Loader

Hello my name is Sara and I am a new member of the forum.
I'm ssing ChronoForms v4 and Joomla 2.5.5 for a few months and I found a problem: I'm trying to organize a sort of manager registrations for events of an organization of birds's breeders.
I created the tables for the user registry to the organization("anagrafica"), data for birds ("uccelli") and a table for entry to the event in which are stored on the user cf_id, bird cf_id and price of bird. I want to load data from tables "anagrafica" and "uccelli" using the code stored on table "iscrizioni".
I tried to do following what "admin" said in this post http://www.chronoengine.com/forums/index.php?option=com_chronoforums&cont=posts&f=26&t=22242 but data are not loaded into the array; using debugger event the array is empty..

Hi Sara,

Welcome to the forums.

Can you write a working SQL statement for your tables ? if you can then this may help us find the correct actions combinations, right now I can't understand the relations between your tables clearly.

Regards,
Max

Thanks for the reply admin. I noticed that did not work because I had "forgotten" to create relationships between tables. I created directly with phpmyadmin. Now the array is filled (seen by the debugger) but I can not render the results, what should I post to make you understand?
