Multiple custom radio buttons in flash

Hey all, I’m in the process of evaluating if this will be possible in flash for me to do.

The requirement is to create a survey type user interaction.

The user will have 7 pages of 5 items each page. Each can be answered by Yes or No (therefore the requirement of the radio buttons).

The user is not required to select a item so i don’t need a check to see if it’s selected or not but i need to tally up the items which have been selected ‘yes’ for each page and then have a total tally at the end.

I would like the custom radio button to have 3 graphic events / up (not selected) / over (light grey in the radio box) / selected (darker grey in radio box).

So thats pretty much it! Is this a major job and does it require some advanced coding? Any response will be appreciated.

thanks!
