This script works in test mode but it doesn't work when I am in game. What do I do?

button = script.Parent.Place button2 = script.Parent.Remove player = game.Players.LocalPlayer character = player.Character cone = game.ServerStorage.Cone mouse = player:GetMouse() placementpart = player.Character:findFirstChild("Left Leg")

mouse.KeyDown:connect(function(key) if key == ("p") then print("Placing a cone for".. character.Name) a = cone:Clone() a.Parent = game.Workspace a.Position = placementpart.Position a.Name = (character.Name) end end)

button2.MouseButton1Click:connect(function() b = game.Workspace:getChildren() if b.Name == character.Name then b:Destroy() end end)

This is located in startergui inside a screengui. I have tried it with a normal script already.
