i just checked the translation and the "haz" instead of "has" mistake IS there, BUT!
$_['won_prize1'] = "Haz encontrado y ganado un Nintendo Wii!";
$_['won_prize2'] = "Haz encontrado y ganado una camiseta y un mousepad del Plus!";
$_['won_prize3'] = "Haz encontrado y ganado un monitor LCD Samsung!";
$_['won_prize4'] = "Haz encontrado y ganado un PlayStation 3!";
$_['won_prize5'] = "Haz encontrado y ganado un Xbox 360 Elite!";
$_['won_prize6'] = "Haz encontrado y ganado una camizeta y un tazón del Plus!";
The mistake is in all the prizes. So he could have won something else
(lol i shouldnt copy paste when translating =P)
