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)
