Relationship between two tables

I have a project with the following characteristics:

Mysql tables:

Table customers (cliente_id, name, email address)
Table processes (process_ID, processo_numero, Arquiquo)
Table clientes_produtos (produtos_produto_id, clientes_cliente_id)

The relationship between the tables is OK: insert page register successfully process data in the table and writes the process ID of the client relationship on the table without problems.

Page processos_results:
This page lists all the cases registered in mysql. The recordset process was created automatically with the DataAssist. I show the fields processo_numero and file to download, no problems. The customer need not enter into search forms for listing the processes as they are filtered by customer ID (variable section) and I have done tests and it worked.

ISSUE:

My problem is in showing a field with the NAME of the customer linked to the process in the RESULTS page.
What I have done to try to solve:
1. I created a RECORDSET_CLIENTES to display just the client (name) linked to the process.
2. I tried to follow the tutorial post "Display data from related tables in results" in the forum but had no success. I created the second Recordset (RECORDSET_CLIENTES). But it really did not understand the steps to create a form variable and then move the second Recordset (RECORDSET_CLIENTES) into the loop.

HELP:
1. Please I need help on this issue. I think the tutorial post which I refer is incomplete because it ends without solution
2. Where can I find a complete tutorial and well-documented and preferably with the screens. The DataAssist has many tutorials and what I found was a tutorial file giving a perfect explanation for how the relationship between the tables but does not show how SHOW (results), edit or delete related data between them.

Thanks,
