Hey superguppie i have already have my pagesize equal to 1. My problem is:

How to keep the radiobutton's value after i click "Next Question" or "Previous Question". Let me show you what i have done so far... 

I want when i click next to show another question and keep the value the user clicked and when i click previous to "read" the value that the user clicked on the previous question. From my search so far i think that i have to do something with the QuestionGroups and use a session or a viewstate to keep the value. Sorry but I dont know much and i am trying to learn :(
