How do I activate a script after I click a button?

Because I have this FPS game, with a Choose a class gui in it, and I want the FPS script to kick in AFTER they choose a class, How can I make that happen?

game.StarterGui.Class.Main.LocalScript.Disabled = true

function Disabled() if game.StarterGui.Class.Main.TextButton.onClicked == true then game.StarterGui.Class.Main.LocalScript.Disabled = false end end

Will this work?
