haha.
ari's right and also one other thing.
make sure you have exactly the named quest item.
sometimes you can have 'the green leggings' or 'the green leggings of strength' but the quest called for 'the green leggings of running real fast so you can get away from those monsters that are chasing you with nasty weapons'.
all green leggings are not created equal. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
