Well, i think i may be asking a question that hasnt been asked yet [i'm embarassed to say i didnt read all 55 pages of this thread, though i know i should have- sorry!]

i run birthday parties for children, where we play safe foam sword games, and i'm trying to use zen cart to accomplish 'purchasing' those bday parties.

the issue i'm having is that i need attributes to do multiplication off of each other.

there are 3 package levels, which cost x or y amount per hour. but that hourly rate can be changed based on the number of participants.

eg: the basic package is $75 per hour, for 20 participants [it cost an additional $50 per hour for each 10 kids above that].

a parent wants a party for 3 hours, for 40 kids.
(75 + 100) * 3

how do i get the attribute controller to do this for me? the main issue i'm having is that i need to use 'price factor' with an offset of -1 to get it to *add* cost, but i can't get the base price to change according to the package level, so all of the math is based on the lowest priced package [the $75 basic, as opposed to the $125 dollar Full Package or $250 Deluxe Package]

can Zen Cart do this for me? or do i have to make 3 different products for the 3 different package types?
