Radio List assistance

Hi All,

this is probably really basic but I am stuck.

basically I have a radio list (call it list a) with values in it, these are dynamic so there could be up to 10 options in it.

what i am trying to do is when an option on list A is selected i.e option 1 is selected it will tie up with a value relevant to the option

i.e if the selection made is the 2nd option on list it will also select the session variable called dynamic2 it will then update one of the stored session variables to have both values added up.

i hope this is clear enough?

thanks,

Arran
