[jQuery] [validate] assigning numeric values in dynamic forms

[jQuery] [validate] assigning numeric values in dynamic forms


I'm not even sure if that title is correct, but I was looking at this
demo for dynamic totals:
http://jquery.bassistance.de/validate/demo/dynamic-totals.html
and was wondering if there was some way to assign specific values to
certain menu items. For example, if I chose Learning jQuery as an
item, a value of 10 would appear next to it. Also, would there be
some way to instead make a menu item a multiplier, as in, if I added
an item and chose jQuery in Action, it would multiple whatever value
was currently there by 3? Thank you for any help.
I am quite new to jQuery, don't know any programming languages and am
going through the jQuery for Absolute Beginners at Theme Forest.
