Condition change on version 1.7.6.1

[chris.panxhi]

Hello guys,

I would like to change the product condition on the product page. I tried many ways to change it but no one worked. 

I have changed 3 files which i found on other topics and nothing was changed. And also i made changes on product table on condition field.

Classes/product.php

Src/prestashopbudle/form/admin/product/productoptions.php

Src/adapter/presenter/product/ProductLazyArray.php

Any idea?
