Why is my move tool script not working for normal players?

i have a problem where a tool i made is not working when you play like a normal user, it only works in Roblox studio

--This script is a normal script --the parent is a tool witch has a child called Handle --tools parent is inside starterPack

-- script made by trommestian03 with help from youtube

while game.Players.LocalPlayer == nil do
    game.Players:GetPropertyChangedSignal('LocalPlayer'):wait()
end

local player = game.Players.LocalPlayer --getting player
print(player.name)
local mouse = player:GetMouse() --getting mouse
local mtarget                --getting mouse target
local down                  
local holding = script.Parent.holding
local sb                        --selectionBox
local dummyblock                --dummblock test
local ready = false             --setting debounce
local tool = script.Parent      --getting tool

tool.Activated:connect(function()
    ready = true
    print("hello")
end)

tool.Unequipped:connect(function()
    ready = false
end)

function clickObj()
    if mouse.Target ~= nil and mouse.Target.Name ~= "Baseplate" then -- moving and spawning a selectionBox
        if ready then
            mtarget = mouse.Target
            print(mtarget)
            mtarget.Anchored = true
            mouse.TargetFilter = mtarget
            print(mouse.TargetFilter)
            down = true
            holding.Value = true            

            local selectionBox = Instance.new("SelectionBox")
            selectionBox.Adornee = mtarget
            selectionBox.Color3 = Color3.new(1,0,0)
            selectionBox.Parent = mtarget
            sb = selectionBox



        end
    end
end

mouse.Button1Down:connect(clickObj) -- testing for mouse butto press

function mouseMove()  -- making block follow the mouse
    if down and mtarget then
        local posX,posY,posZ = mouse.Hit.X,mouse.Hit.Y,mouse.Hit.Z

        --dummyblock.Position = Vector3.new(posX,posY,posZ)

        local fposX = math.floor(posX)
        local fposY = math.floor(posY)
        local fposZ = math.floor(posZ)

        mtarget.Position = Vector3.new(fposX,fposY,fposZ)




    end

end
mouse.Move:connect(mouseMove)
