would this code work?

Hello,

This looks like a great module. I'd really like to use it but I haven't gotten very far with my php lessons yet. :)

What I want to do is to set it up so that the product price is $6.50 and each additional is $5.00. So if you're buying two, the total price is going to be be $6.50+5.00=$11.50.

Does this code look like it would work?

$item->price = $item->price+[[quantity]-1]*5;

In case my php is more horrible than I think, it's supposed to subtract 1 from the quantity, multiply that by 5, then add it to the price. So a quantity of 3 would be: price + (3-1)*5.

Thanks!
