Sorry for the necro, but you created such a wonderful tutorial and if other people have the same problem as me hopefully this can help.
I followed every step, but for some reason it didn't work at all, and when I go to type something it says there's a trigger error updating the chat label.
EDIT: I forgot to set a trigger to run the init action. The box appears but it does nothing. There are no errors, and no text appears in the chat box.
