Add Validation by spsingh

Hi,

I created a questionarrie, which users have to fill before product is added to cart.

Questionarie working fine (show error if required filed are not filled),  but product still added to cart if user click on the 'add to cart' button.

So how can i track ajax cart to stop it to add in cart if form is not filled.
