Yes I know... Works in studio, doesn't work in-game?

Basically I have a script to cut down a tree. Works fine and everything in studio, but when it comes to playing normally it just doesn't do a thing or even say anything in the dev console. Here is the script, if you have any idea that would be great.

local tool = script.Parent
local player = tool.Parent.Parent
debounce = true
player:WaitForDataReady()

function Collect(mouse)
    if mouse.Target ~= nil then
    if mouse.Target.Parent.Name == "Tree1" then
local thetree = mouse.Target.Parent
    if (mouse.Target.Position - player.Character.Torso.Position).magnitude <= 20 then
    if thetree.Hide.Value == 0 then
    if debounce == true then

local origwalkspeed = player.Character.Humanoid.WalkSpeed   


    debounce = false

    player.Character.Humanoid.WalkSpeed = 0

    local bg = Instance.new("BillboardGui")
    bg.Parent = player.PlayerGui
    bg.Adornee = player.Character.Head
    bg.Size = UDim2.new(4, 0, 4, 0)
    bg.StudsOffset = Vector3.new(0, 5, 0)
    local il = Instance.new("ImageLabel")
    il.Parent = bg
    il.Image = "http://www.roblox.com/asset/?id=420600020"
    il.Size = UDim2.new(1, 0, 1, 0)
    il.BackgroundTransparency = 1



    wait(thetree.Time.Value)

    bg:remove()

    player.Character.Humanoid.WalkSpeed =  origwalkspeed

    player.leaderstats.Wood.Value =     player.leaderstats.Wood.Value + thetree.GiveAmount.Value

    debounce = true
    thetree.Hide.Value = 1

    end
    end
    end
    end
    end
end


script.Parent.Selected:connect(function(mouse)
mouse.Button1Down:connect(function() Collect(mouse) end)
end)
