Why is my projectile not firing?

local tool = script.Parent
local projectile_shooter = tool.Handle
local repstorage = game.ReplicatedStorage
local bullet = repstorage:WaitForChild("Bullet")
local effective_distance = 200
local speed = 200
local target = nil
local dmg = 10
while tool.Equipped do
    wait()
    tool.Activated:Connect(function()
        for i, v in pairs(game.Workspace:GetChildren()) do
            local human = v:FindFirstChild("Humanoid")
            local torso = v:FindFirstChild("UpperTorso")

            if human and torso then
                local newray = Ray.new(projectile_shooter.Position, (torso.Position - projectile_shooter.Position).Unit * effective_distance)
                local hit, position = game.Workspace:FindPartOnRayWithIgnoreList(newray, {projectile_shooter})

                if hit == torso then
                    target = torso
                end
            end
        end

        if target then
            local torso = target
            projectile_shooter.CFrame = CFrame.new(projectile_shooter.Position, torso.Position)
            local newbullet = bullet:Clone()
            newbullet.Parent = game.Workspace
            newbullet.Position = projectile_shooter.Position
            newbullet.Velocity = projectile_shooter.CFrame.LookVector * speed

            newbullet.Touched:Connect(function(hit)
                local human = hit.Parent:FindFirstChild("Humanoid")
                if human then
                    human:TakeDamage(dmg)
                end
            end)
        end

    end)
end

I was watching a raycasting tutorial and modified some of the code to make a gun. For some reason the projectile is not firing. I would like some help as to why.
