Lol, this thread is mad funny. Forget about alias's and all that stuff. Just go onto the quest stages tab of your quest, click onto the stage you want to add the gold, and add a new property to the script fragment there, of the type "miscitem" and call it Gold001, and then use autofill, and it will fill it automatically. Then back in the script just type this:
Game.GetPlayer().Additem(Gold001, 2000)
