Writing information to and reading information from a shared object

I have been asked to set up a log-on and tracking system using shared objects.
I have built the log-on section you can write a user name and pasword to the sharedobject text file. But what I want to do is to be able to write the last position a person attended within a specific template and also to relay any scores that they got.
I also have the tracking system set up that tells the user what sections they have completed or are in the process of completing and the exact same process in place for the topics within the section.
I tried to get the _current frame of the last frame they visited but unfortunately this won’t work here. I was wondering if there is any way to get this to work.
Cheers
