Help with displaying multiple choice options

Hi All,

I am creating a presentation which essentially has 4-5 steps and each step has 4-5 multiple choices from which a user can make the needed selection and they get a report based on the options selected.

What I need help here is with when someone is on Step2 and clicks the previous button he/she should be able to view the option that was selected in Step1. Same goes for all the steps until they reach the final stage.

I am attaching a test flash file to give an idea of what I want. If someone can please suggest the code for it will be very helpful.

Let me know if any other information is needed.

Thanks
