By default the system set tax to "0.00".
It is possible to remove the tax field completly to let my paypal system managing it? Because I set my tax system on my paypal account to charge the right amount of tax depend on the location. And when someone complete the form and proceed to the payment, paypal receive this value "&tax=0.00&". I'm good to playing with code so I can remove it manualy directly in the code.
I would just need the location of the file to do it.
Also maybe it's a way to do it without coding it like replace the value with something else or somewhere to desactive it?
