Why won't my gui go away when unequipped?[Solved]

Hello! I am making a chemical thrower gear from Bioshock! I have a gui for it and I made it so when I equip the Tool it becomes visible. However it does not go away when i try this part:

local Tool = script.Parent;

enabled = true
function onButton1Down(mouse)
    if not enabled then
        return
    end

    enabled = false
    mouse.Icon = "rbxasset://textures\\GunWaitCursor.png"

    wait(7)
    mouse.Icon = "rbxassetid://207207462"
    enabled = true

end

function onEquippedLocal(mouse)
game.Players.LocalPlayer.PlayerGui.ChemGui.Frame.Visible = true
    if mouse == nil then
        print("Mouse not found")
        return 
    end

    mouse.Icon = "rbxassetid://207207462"
    mouse.Button1Down:connect(function() onButton1Down(mouse) end)
end
function Unequipped(mouse)
    game.Players.LocalPlayer.PlayerGui.ChemGui.Frame.Visible = false

end
Tool.Unequipped:connect(UnequippedLocal) --Where I have trouble
Tool.Equipped:connect(onEquippedLocal)

I don't know why it is doing this but here is what is in the output: 11:24:54.168 - Attempt to connect failed: Passed value is not a function 11:24:54.169 - Script 'Players.Player1.Backpack.Flame Thrower.Local Gui', Line 34 11:24:54.170 - Stack End 11:24:56.097 - attempt to call a nil value

Any help?
