Common Problem: Works in studio but not in real game?

HopperBin script works in studio but won't work in real game. Used to pick up items by clicking on them, and dropping them by clicking again.

holdRadius = 7
maxSelectRadius = 10

local position = Instance.new("BodyPosition") 
position.Name = "Pos"
position.maxForce = Vector3.new(100000,100000,100000)

local object = nil 

function onButton1Down(mouse)
    if mouse.Target ~= nil then 
        if (mouse.Target.Position - game.Players.LocalPlayer.Character.Head.Position).magnitude <= maxSelectRadius and not mouse.Target.Anchored then 
            position.Parent = object
            position.position = game.Players.LocalPlayer.Character.Head.Position + (mouse.Hit.p - game.Players.LocalPlayer.Character.Head.Position).unit * holdRadius
    end
end

function onButton1Up(mouse)
    object = nil
    position.Parent = nil
    down = false
local force = Instance.new("BodyForce")
	force.force = Vector3.new(0,90,0)
	force.Parent = object
	wait(2)
	force:Destroy()
end

function onMove(mouse) 
    if down then
        position.position = game.Players.LocalPlayer.Character.Head.Position + (mouse.Hit.p - game.Players.LocalPlayer.Character.Head.Position).unit * holdRadius
    end
end

function onSelected(mouse)
    mouse.Button1Down:connect(function() onButton1Down(mouse) end)
    mouse.Button1Up:connect(function() onButton1Up(mouse) end)
    mouse.Move:connect(function() onMove(mouse) end)
end

script.Parent.Selected:connect(onSelected)
script.Parent.Deselected:connect(onButton1Up)

help?

Problem

The only problem I can see is that since it works in studio and not in server it should be a latency problem, this happens because in studio everything is pretty much local so you don't have to wait for a server to create stuff so your local scripts run instantly. In server this doesn't happen as when a local scripts cause upons something in player or character that is server-sided then the local script is "local" which makes it run faster then the server can respond.

Solution

repeat wait() until game.Players.LocalPlayer.Character--To the top of every local script
