How do I make a tool activate a frame?

My attempt with no errors:

local Tool = script.Parent -- Get tool

Tool.Equipped:Connect(function(Mouse) -- When tool equipped
    Mouse.Button1Down:Connect(function() -- When tool is used
        script.Parent.Parent.PlayerGui.MainScreenGui.Information.Visible = true
    end)
end)

However, it does not do what it's supposed to do.
