Script doesn't do anything but doesn't give any error messages either?

So I have this script here, which I've had some issues with in the past. This script works fine according to the output, because it doesn't give any error messages or anything. But the problem is: The script doesn't do anything either, I don't know what happened. Can someone help?

Script:

local gun = workspace.Turret.Gun
local originpoint = gun.CFrame.p

script.Parent.Radar.Radar.Touched:connect(function(plr)
    if plr.Parent:IsA("Model") and plr.Parent:FindFirstChild("Humanoid") and game.Players.LocalPlayer.Character:FindFirstChild("Head") then
    script.Parent.Gun.alert:Play()
    local ignore = {script.Parent,game.Players[plr.Parent.Name]}
    local ray = Ray.new(originpoint,plr.Parent.Head.CFrame.p.Unit*100)
    local gun,position = workspace:FindPartOnRayWithIgnoreList(ray,ignore,false,true)

    local beam = Instance.new ("Part")
    beam.BrickColor = BrickColor.Red()
    beam.Material = "Neon"
    beam.Transparency = 50
    beam.Anchored = true
    beam.Locked = true
    beam.CanCollide = false

    local Distance = (script.Parent.Gun.CFrame.p-position).magnitude
    local distance = Distance/8
    repeat
        beam.Size = Vector3.new(.15,.15,distance)
        beam.CFrame = CFrame.new(script.Parent.Gun.CFrame.p,position)*CFrame.new(0,0,-distance/2)
        distance = distance*2
        wait (0.01)
    until distance == Distance*2

    beam.Touched:connect(function(hit)
        if hit.Parent:IsA("Model") and hit.Parent:FindFirstChild("Humanoid") then
            local human = hit.Parent:FindFirstChild("Humanoid")
        human:TakeDamage(10^308)


      

  

    game:GetService("Debris"):AddItem(beam,.1)








	game:GetService("Debris"):AddItem(beam,.1)

end
end)

end
end)

Thanks for helping, it is apperciated!
