You say in this page:

<< If we want to know the number of cards, we pass "cards" to the
function this way:
the number of cards
 which can also be written:
number(cards)
 Revolution then goes through the stack and adds all the cards to get a
total, which is sent back to your script.>>

Does really Revolution go to the stack and *count* the cards?
If a stack is in memory, I thought that the number of cards is written
down somewhere in the stack... really, not?
And so, for the number of controls??
