get or post

Hello: I have a script that gathers user input from 5 different successive screens (i am passing along the data from previous screens in hidden form elements), but I am noticing that if you need to go back one screen, the browser does not show you the form with your beautiful input but rather a "page expired" message (depending on browser) asking if you wish to repost...Needless to say if you make significant amounts of input you will be pissed if you "lose" it all if you hit the back button... Questions: is this due to using a post rather than a get form action? Will a form GET fix this error? What are the size limits to a GET method? (I am using some textareas, so they could get long-ish)... Any answers much appreciated... Luis __________________________________________________ Do You Yahoo!? Thousands of Stores.
