Help w/PayPal Shopping Cart in AS2

[AlxSTi]

Edit - Mods, you can delete this. I got it figured out.

Hi - I am using a Flash AS2 template for a PayPal shopping cart on my site. As the code is now, a new shipping charge is added to the buyers total for every item added. I would like it to have only 1 shipping charge, no matter how many items are added!

Below is the code for the cart.. any help is greatly appreciated.

import caurina.transitions.Tweener;
cartItems = new Array();
itemNr = -1;
itemQty = 1;

cartin = false;
ctrl_mc.cart_mc.onRelease = showCart;
attachMovie("cart","cart_mc",15000,{_x:Stage.width});
cart_mc.title_txt.autoSize = true;
cart_mc.title_txt.text = "YOUR CART IS EMPTY !";
cart_mc.bg_mc._height = cart_mc.title_txt._y+cart_mc.title_txt._height+15;
cart_mc.bg_mc._width = cart_mc.title_txt._width+100;
cart_mc._y = (Stage.height-cart_mc.bg_mc._height)/2;

totalprice = 0;
totalship = 0;
cart_mc.createEmptyMovieClip("cartitems_mc",10);
cart_mc.cartitems_mc._y = cart_mc.title_txt._y+65;
cart_mc.cartitems_mc._x = cart_mc.title_txt._x;

According to PayPal's site:

Number of items. If profile-based shipping rates are configured with a basis of quantity, the sum of quantity values is used to calculate the shipping charges for the transaction. PayPal appends a sequence number to uniquely identify the item in the PayPal Shopping Cart (e.g., quantity1, quantity2). Note: The value for quantity must be a positive integer. Null, zero, or negative numbers are not allowed.

This is also the code for PayPal Checkout:

function checkOut() {
var paypal = new LoadVars();
paypal.cmd = "_xclick";
paypal.cmd = "_cart";
paypal.upload = "1";
paypal.handling = "0";
for (pp=0; pp<=_root.cartLength-1; pp++) {
paypal["item_name_"+(pp+1)] = cartItems[pp][3];
paypal["quantity_"+(pp+1)] = cartItems[pp][1];
paypal["amount_"+(pp+1)] = cartItems[pp][2]
}
paypal.business = payedto;
paypal.currency_code = currcode;
paypal.shipping_1 = totalship;
paypal.send("https://www.paypal.com/cgi-bin/webscr","POST");
}

glad it all worked out for you.
