why this gun shooting script isn't working at all?

so i tried to make a gun. first i tried to make a shooting script that just shoots a small yellow brick here's the script:

local tool = script.Parent
local shootpart = tool.Shoot
tool.Activated:Connect(function()
		local bullet = Instance.new("Part")
		local bulletscript = tool.Bullet:Clone()
		bullet.Size = Vector3.new(0.1,0.1,0.1)
		bullet.BrickColor = BrickColor.new("New Yeller")
		bullet.Parent = workspace
		bulletscript.Parent = bullet
		bulletscript.Disabled = false
		bullet.Position = shootpart.Position
		bullet.Velocity = shootpart.CFrame.LookVector*10
end)

doesn't work of course
