Local Function Won't Fire? [Inside Tool] Tool Unequipped Doesn't Remove GUI?

This is probably one of the most hardest scripts I've ever tried to dealt with, and it seems that this button still won't work. I've got the GUI to pop up, but whenever I click the button, the function won't work.

Function:

local tool =  script.Parent
local button = script.Parent.ControlsGui.TextButton
local Debounce = true
local Active = false

local CoolDown = 0.01
local function Start()
tool.rMovement.Disabled=true
    tool.lMovement.Disabled=true
    tool.HandValue.Value = 1
        tool.GripPos = Vector3.new(0.5, -0.5, -0.3)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, -1, 0)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, -1.5, 0.5)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, -1.5, 1)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, -1.5, 1.5)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, -1, 2)
        wait(0.01)
        tool.GripPos = Vector3.new(1, -0.5, 2.5)
        wait(0.01)
        tool.GripPos = Vector3.new(1.5, 0, 3)
        wait(0.01)
        tool.GripPos = Vector3.new(2, 0.5, 3)
        wait(0.01)
        tool.GripPos = Vector3.new(2.5, 1, 3)
        wait(0.01)
        tool.GripPos = Vector3.new(3, 1.5, 3)
        wait(0.01)
        tool.GripPos = Vector3.new(2.5, 2, 2.5)
        wait(0.01)
        tool.GripPos = Vector3.new(2, 2.5, 2)
        wait(0.01)
        tool.GripPos = Vector3.new(1.5, 3, 1.5)
        wait(0.01)
        tool.GripPos = Vector3.new(1, 3.5, 1)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, 3, 0.5)
        wait(0.01)
        tool.GripPos = Vector3.new(0.5, 2.5, 0)
        wait()
    tool.lMovement.Disabled=false
end

button.MouseButton1Down:connect(function()
    if Debounce then 
    Debounce = false
        Start()
    wait(CoolDown)
    Debounce = true
  end
end)


function onKeyPress(actionName, userInputState, inputObject)
    if userInputState == Enum.UserInputState.Begin then
        if Active and Debounce then
        Debounce = false
            Start()
        wait(CoolDown)
        Debounce = true
    end
    end
end

game.ContextActionService:BindAction("keyPress", onKeyPress, false, Enum.KeyCode.G)

I have no errors, but I don't know why it won't fire, or work.

local tool=script.Parent
local gui=tool.ControlsGui

tool.Equipped:connect(function()
    tool.rMovement.Disabled=true
    tool.lMovement.Disabled=true
    local Player=game.Players:findFirstChild(tool.Parent.Name)
    if Player and tool.Parent:findFirstChild("Humanoid") then
        local c=gui:Clone()
        c.Parent=Player.PlayerGui
    end
    if tool.HandValue.Value==1 then
        tool.lMovement.Disabled=false
    else tool.rMovement.Disabled=false
    end
end)

tool.Unequipped:connect(function()
    gui:Destroy() -- this actually removes the GUI from the tool, so idk any alternative method.
end)

-The thing is whenever I try to use WaitForChild, in the Output, it always gives me Infinite Yield Possible. -Also I have another GUI that's inside the Tool, but that has no errors. It works totally fine.

If you could help, that would be great.
