How to change the numer Related products in a row?

Hello,

On this page you can see the problem. I like to change the number of Related products from 4 to 3 but I can't find that option in Virtuemart backend. Does this have to be done hardcoded somewhere in a file or something?
Thanks!

Hi,

open
administrator\components\com_virtuemart\html\shop.product_details.php

find line:

$q .= "AND FIND_IN_SET(#__{vm}_product.product_id, REPLACE(related_products, '|', ',' )) LIMIT 0, 4";


and replace 4 with 3

Thanks! that did the trick
