hide/show button

Are your boxes part of a question? If so, you can use the question variable to help you with what you want to do.I do something similar by doing the following:I have an action that says if the question is correct, then I allow the user to move on, but in your case you could use it to show the Next button. I would provide the user with a Process Question button (provided that it is a question we are talking about with the check boxes) that has 2 action on it: 1)for processing the question and then 2) if correct allow the next button to show.I hope that helps.
