disble comments

IM using marketpress, with frame market/gridmarket theme. some pages like this one..

http://www.ybrmarket.com.au/blog/store/products/my-product/

I dont know how to disable the comments.. As the page is somewhat generated by marketpress.

I went through a few gridmarket files like mp_product.php and changed comments template to false but that didnt have an effect. Any Ideas?
