Dear all,
I am using the extension "Go to detail page". It allows only select the
primary key from one table to show the details of that table, what should I 
do
if I want to extract the details from 3 tables and show in the
"detailed-page.php"?

Thanks you in advance.

Then you need to create an advanced recordset query (click Advanced...) that
 joins the tables together on a common column.
