Show submit button after text is entered
I want to force the user to enter their name. I have already set up everything up including the variable for username. What I want is for the submit button to be shown only if text is entered in the text entry box. Currently they can leave the box empty and click submit. This throws the rest of the video off as there are now weird spaces and seemingly random " 's " floating because a name was not entered.
Is this possible?
