Amsterdam Tix

HI, I'M FROM ITALY AND FEW DAYS AGO I BOUGHT 2 TICKETS FOR THE AMSTERDAM SHOW ON INTERNET (WWW.TICKETMASTER.NL).
THERE WERE LEFT REALLY FEW TICKETS AVAILABLE AND SO I COULD ONLY BUY "CATEGORY 8" TICKETS.
I THINK THEY ARE NOT "STANDING TICKETS" SO I WOULD LIKE TO KNOW IF COSTING MORE THAN THE OTHER (MINE) I COULD ATTEND THE SHOW IN THE FIELD EVEN IF I HAVE NOT THE CORRECT TICKETS.
IF ANYONE WHO HAS STANDING TICKETS WOULD LIKE TO EXCHANGE WITH MINE (41.50 EURO) PLEASE CONTACT ME AT JONATHAN07@INTERFREE.IT
THANK YOU
