This isn't working! Help?

I'm trying to make this shield that defends against bullets and paintballs, but it isn't working!

function onTouched(part)
	if part.Name == "Bullet" or "Paintball" then
		Shield = Instance.New("Part")
		Shield.Size = Vector3.new(.2,.2,.2)
		Shield.CanCollide = false
		Shield.Parent = game.Workspace
		Shield.BrickColor = ("Really red")
		Shield.Position = script.Parent
		
		local mesher = Instance.new("BlockMesh")
		mesher.Parent = Shield
		mesher.Scale = Vector3.new(0.2, 0.2, (script.Parent.Position - onTouched(part).Position).magnitude)
		
		explosion = Instance.new("Explosion")
		explosion.Parent = game.Workspace
		explosion.Position = part
		
		wait(1)
		part:remove()
	end
end

Isn't the method at the end of your script wrong? part:remove() isn't a method.

part:Remove()

is a method, other than that I don't know how to help.
