Skip the last question in a questionnaire

I have a followup question that is conditional on a previous scale response item. This pair are the last 2 in a questionnaire. If they answer A on the first question, they should not skip and answer the second question. If they answer B on the first question, they do not need to answer the second question and so should finish the questionnaire.

All the documentation says that you have to enter a variable name in the SkipTo column, but what if you aren't skipping anywhere but the end? Is there a way to skip to "end" or something?
