Multiplayer Quest System

I've been looking for a Quest System that is useable in Bnet games, and found one here, but I can't get it to work.

It uses a variable, "TheHero", to detect if a quest has been completed/if the requirements have been completed/etc., but "TheHero" is set at the beginning of the map on a unit that is pre-placed on the map, and I need it to be set after a unit has been created that a player has selected. So basically, I need "TheHero" to be a unit-array, but its been coded as if its just a unit variable.

Answer here.
