Maintain user-entered values in a multi-step wizard
I'm building a typical multi-step "wizard" interaction with "Back" and "Next" buttons. I know how to create/set variables and redisplay them elsewhere, but that's not what I need to do here. Basically, I need each page to maintain the values the user enters after they leave the page (advance to later pages in the wizard)... so that if they come "Back" to any page, the values they entered are still there. How would I accomplish this? I'm struggling right now. Each page has some combination of input (text) fields, radio buttons, and dropdowns.
