Removing GM: from gamemode functions.

Trying to get rid of GM: from a gamemode but keep gives me “attempted to call method”.
Any idea what is the problem?

function SetupCoolDownWeapon(wep)
	if not wep.WElements and not wep.VElements then
		wep.DrawWorldModel = CDDrawWorldModel
		wep.DrawWorldModelTranslucent = wep.DrawWorldModel
		wep.GetViewModelPosition = CDGetViewModelPosition
