Hello,
I got a big problem and hope the paypal developer can shed some light on it.
I've created a set of code with "add to cart", "shipping charges", and "desire quantity".
User should select how many and which location they want, then click 'add to cart' to pay via paypal.
However, I just realized that if I didn't select the quantity and location, then a customer can simply select "add to cart" to bypass the shipping charges. That's a big problem for me.
May I know what additional codes I should add to force the customers to select location and quantity before they access the paypal payment page? Or after clicking "add to cart' without select anything, the paypal page shows some kind of 'invaild selection' message and urge the user to go back before pay out?
here is the site I build (

Many thanks in advance.
