Hi @BethB5,

As long as you can edit the question, you should be able to save it.  If you're using classic quizzes, this is a 2-step process.  First you have to hit the update button for the question, then you need to scroll down to the bottom of the page once all questions are updated and hit the main save button.  If you only do one or the other of those (or in the wrong order), your changes wouldn't stick.
