European VAT number module, add customer to a group if valid

[sixthmind]

I am using European VAT number checking module and currently using option: Enable checking of the VAT number with the WebService.

 

What I need to do is: if VAT number is valid, I want the user to become a member of a specific group. I tried couple of things, but I cannot make it work. If somebody could point me to the right direction, it would be really appreciated.

 

What I discovered so far:

I can add customer to a group like that I believe: $customer->addGroups(array(2));

 

I am just struggling with if statement and where to put it at the moment. I am thinking that the code should be put somewhere in Address.php in

public function validateController($htmlentities = true)

 

 

If somebody could help me, I would appreciate it.
