Why is my GUI not changing from a script? It should be saying yes or yo when I press a button.

Here is the localscript on a ScreenGui object, wordDis is also a child of ScreenGUI. `` function displayWord(key)

if(key == Enum.KeyCode.R) then
    script.Parent.wordDis.Text = "yes"
end

if(key == Enum.KeyCode.F) then  

    script.Parent.ScreenGUI.wordDis.Text = "yo"
end


end



game:GetService("UserInputService").InputBegan:connect(displayWord)
