group door script is killing everyone?

When you touch the door, you die. The group you get VIP for is http://www.roblox.com/My/Groups.aspx?gid=1089722 Is there anything wrong with the 7th line?

debounce = false

script.Parent.Touched:connect(function(hit)
	if (hit) then
		if (hit.Parent) then
			if (game.Players:GetPlayerFromCharacter(hit.Parent)) then
				if (game.Players:GetPlayerFromCharacter(hit.Parent):IsInGroup(184188)) then
					debounce = true
					script.Parent.Transparency = 0.5
					script.Parent.CanCollide = false
					wait(2)
					script.Parent.Transparency = 0
					script.Parent.CanCollide = true
					debounce = false
				else 
					hit.Parent.Humanoid.Health = 0
				end
			end
		end
	end
end)
