How do I fix this Gui timer script based on a value that changes depending on the input?

local Frame = script.Parent.Parent.PlayerGui.ScreenGui.Frame.TextBox.Text
local bacon = script.Parent.Parent.Folder.Timer.Value

if script.Parent.Parent.Folder.Timer.Value.Changed() then
	do script.Parent.Parent.PlayerGui.ScreenGui.Frame.TextBox = script.Parent.Parent.Folder.Timer.Value
 for i=1,bacon do
wait(0.3)
		script.Parent.Parent.Folder.Timer.Value = script.Parent.Parent.Folder.Timer.Value - 1
		script.Parent.Parent.PlayerGui.ScreenGui.Frame.TextBox = script.Parent.Parent.Folder.Timer.Value

end
if bacon == 0 then
	end
end
end

11:11:29.919 - Timer is not a valid member of Folder 11:11:29.919 - Stack Begin 11:11:29.920 - Script 'Players.Kitorari.PlayerScripts.LocalScript', Line 2 11:11:29.921 - Stack End

I'm trying to get this gui timer to work, and its saying Timer doesn't exist, yet it does. Not sure what to do...

The whole thing is based on the timer value...
