Topic: Show Customer ID ( from table ) on form.

How can I show the CUSTOMER_ID on the invoice form. Like in a text box under the Customer Combo box. I need to see the customer ID on the form already.

I managed to add a textbox on the form that shows the customer_id, but it does not update when I change the customer.

Please help?

try to add
$Ajax->activate('title');
title is your variable name which you want to refresh
