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.");
	}
}
