The Underscore Archives

hello _
ive been building a gallery site for a client. ive written a class that 
extends movieclip and i use it to create instances that display the 
paintings and all the relevant details
the class also attaches a button that is supposed to link to paypal

my prob is this
the compiler keeps throwing up an error when i use POST as method?
if i put any thing else in there it obviously complains that i can only 
use GET or POST??
here's an example

attachMovie("buy_now1", "buy_now", this.getNextHighestDepth(), {_x:790, 
_y:280}).onRelease=function(){
                var business="user_email at domain.com";
                var item_name:String=$picName;
                var amount:Number=$picPrice;
                var no_note:Number=1;
                var currency_code:String="GBP";
                var lc:String="GB";
                var bn:String="PP-BuyNowBF";
                
getURL("https://www.paypal.com/cgi-bin/webscr","_blank","POST");
};

anyone no where im going wrong?


TIA

simon
