Small adjustment

Hi , I have a creloaded pro 6.2 shop with a lot of custom modifications. I need help fix this: On the attachmet you can se how my product info page look like. I need you to change the defalut value on the subproduct lines from 0 to 1. I have tryed to do this my self, with the result that when you click on one cart, it would add one of all the subproducts. Should be easy to fix. I need to know which lines to change, as i should apply this fix to more shops.
