MX 04 template quiz change

Hi folks,

Thank for the help to get me this far… anyways, ive now made a quiz based on the template with MX04 but would like to change it so that i can have a back button… is this easily done.?

Currently the quiz only allows you to see 1 question at a time and you must submit an anwse before preceeding, i would like it to allow users to go back and forth through the questions…

another query also, is that if i want to send the results of the quiz to the marker, i assume i would have to hav login page to ensure each user was unique…

*if flash is the wrong tool for the job too, let me know,

the current quiz is here
