put the return item in the else.. you have an extra } as well
Code:
sub EVENT_ITEM {
if (($platinum >= 1000) && plugin::check_handin(\%itemcount, 132595 => 1)) {
quest::summonitem(132594);
plugin::Whisper("Here you go $name, remember, I had nothing to do with this.");
quest::exp(1000);
quest::ding();
}
else {
plugin::return_items(\%itemcount);
quest::say("Sorry, $name, but I have no use for that.");
}
}
