Trying to impliment a tracker to save progress for viewing an online web module

[yuencr20]

I'm trying to impliment a tracker to save progress for viewing an online web module for our department. It is a flash module that is broken into four separate modules. We have an existing evaluation form that runs to server, but it only takes info and stores it. Students will need to enter normal demographic information and create a password,but we need it to be possible to save their progress so that they can come back to it later. We don't need it to track too in depth but at least to the module that they have reached. I had planned on just making 4 separate html pages that preceeded each module that only linked to the next, but it seems that people won't be able to finish in it one sitting, hence the tracker is needed. if anyone can help or correspond back with me to get me started that would be much appreciated.

Thanks,
Ryan

Well, there are two parts: remember where they were, and repopulating their answers to date.  The first part is easy, the second, more complicated.
