Spell Casting GameObject

[demonze]

Well i trying to make a little custom pvp area and i need to know if i can make a gameobject (Lever) cast a spell when you use the lever. I tried using

global PVP_Buff = function(plr)
	{		
                .CastSpell(22888);
	};
	.RegisterGameObjectEvent(10000000, 6, PVP_Buff);

its the rally cry spell buff that casts on everyone...but it justs not casting.
