Need some basic component property help

1

i bought this great shopping cart component , but i now i need things changed .
in my support page it says:

The following sets the targetURL field value of the cart:
cartEngine.targetURL = “https://www.myDomain.com/myCustomCart.php”;

but i dont know where to plug this into , or what the process is to changing this property .

thanks for the help :slight_smile:
