Display one element at a time

Nothing seems to work. I have try every thing. At least all of the obvious like pos(array) or $element = current($array) . What I am trying to do : Is to ask questions (the problem I am having, display only one at a time) get answer by using a check box move and display next question (part of the problem) At this point my alternative is to go ahead and print all the questions with check boxs. Not what I wont to do. If any one can help please email me at mcapps@tampabay.rr.com thanks in advance
