server behaviours/eCart/general/set session value
Then:
a/ what would the trigger be, is it dynamic (eg UPS Result...)?
b/ Is the value of the session variable of the posted value from the service list from the checkout page EG "UPS_Service" and is this the session name?
c/ Where do I find the value?
c/ What is a new hidden form element I add to the form and is the form on the confirm page?
d/ Where do I find the same name as the select list on the checkout page.
e/ How do I set the value of this hidden form element to the session variable just created.
