how to make a model spawner tool? [closed]

I have tried to modify parts from similar freemodels but they work only in studio mode and not while playing the game from roblox client.The intended funtion is to spawn a model once when clicked with the tool.Here is what i have(note that this only works in studio testing and not in roblox client in-game):

bin = script.Parent

function onButton1Down(mouse)

local model = bin.tent:clone() 

model.Parent = game.Workspace
model:MakeJoints()
model:MoveTo(mouse.hit.p)

end

function onSelected(mouse) mouse.Icon = "rbxasset://textures\GunCursor.png" mouse.Button1Down:connect(function() onButton1Down(mouse) end) end

bin.Selected:connect(onSelected)
