Why isn't my function even firing?

So I made a keydown function to fire if a value is true, the value is true, but the function isn't firing when I press the hotkey. It works when the value isn't even included. Here is the script:

local Player = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
 showed = false
Mouse.KeyDown:connect(function(Key)
    if ((Key:lower() == script.Parent.hotkeyvalue)) then
        print("Hotkey pushed")
        if showed == false then
            showed = true
        repeat wait(0.01)
        script.Parent.Players.Position = script.Parent.Players.Position - UDim2.new(0.01, 0, 0, 0)
        until script.Parent.Players.Position.X.Scale >= 0.4
        elseif showed == true then
        repeat wait(0.01)
            showed = false
        script.Parent.Players.Position = script.Parent.Players.Position + UDim2.new(0.01, 0, 0, 0)
        until script.Parent.Players.Position.X.Scale >= 0.8 
        end
        end
end)
