Personalization Text Box (Variable)

I created an introductory slide that included a text box variable for the learner name.  I also included a text box "continue" for the learner to move forward after entering their name.  I do not want the learner to move forward until the name text box has name (or text).  I have not used this feature in a while (spoiled by "RISE").  For my current online course, I am required to personalize and have drawn a blank on how to created the slide layer to ensure the learner complete the name field before moving forward.  Please jog my memory.  Thanks!
