give npc money for a spell
 

I am wondering if it is possible to have a quest where if you give an npc money it will cast a spell on you in return. The server is version 60dr2. If this is possible then what would the syntax be to accomplish this. Any help would be greatly appreaciated. Thanks.

sub EVENT_ITEM
{
if($platinum == 30)
{
quest::selfcast(1);
}
}
You can also add silver in, copper in, etc. Make level reqs, all of that.
