Gun script works locally, but doesn't work on a server test?

I have a local script that detects when a tool is activated. When the tool is activated, it fires a remote event that fires a bullet from the gun. It works fine when you play test, but when I test it on a server, it doesn't work. What am I doing wrong?

Edit: I have the print scripts to test what isn't working. The only thing that it printed was "oy mate im activated."

Local Script:

local repStorage = game:GetService("ReplicatedStorage") local remote = repStorage:WaitForChild("Remote")

local repStorage = game:GetService("ReplicatedStorage")
local remote = repStorage:WaitForChild("Remote")


_G.Gun = script.Parent


_G.Gun.Activated:connect(function()
    remote:FireServer()
    print("oy mate im activated")
end)

Script:

local repStorage = game:GetService("ReplicatedStorage")
local remote = repStorage:WaitForChild("Remote")


remote.OnServerEvent:connect(function()

            local Player = game.Players.LocalPlayer


            local Ammo = 5
            local mouse = Player:GetMouse()


            if Ammo > 0 then
                print("Hey I shot a thing!!")
                local Bullet = Instance.new("Part", workspace)
                game.Debris:AddItem(Bullet, 2)
                Bullet.Shape = "Ball"
                Bullet.Size = Vector3.new(3, 3, 3)
                Bullet.TopSurface = "Smooth"
                Bullet.BottomSurface = "Smooth"
                Bullet.BrickColor = BrickColor.new("Dark stone grey")
                Bullet.CanCollide = false
                Bullet.CFrame = _G.Gun.Handle.CFrame
                Bullet.CFrame = CFrame.new(Bullet.Position,mouse.Hit.p)
                local v = Instance.new("BodyVelocity", Bullet)
                v.velocity = Bullet.CFrame.lookVector *90
                v.maxForce = Vector3.new(math.huge, math.huge, math.huge)

            end

end)

Thanks!
