I'd never do it that way. I was just providing a method that would meet spec. There's not even a reason to do what you're suggesting since it's duplication of data (ie - memory issues). But, some caveats to your code. We don't know if N will be integer. We presume it will be, but what about cases 1a, 1b, 1c?

Furthermore, my code has that problem in the case where $1 = 1. in which case you're evaluating ${$1} -> $1 -> 1;

My answer was to generally push these guys in the direction proper, and your reply shows why my initial thought of stripping question from N is bad. I hadn't seen that before a, thanks.

It appears that a lot of people use the ID number, since it appeared on another post as magic cookie. I left a lot of my answer open ended since this is a group project for school, and I think they should be forced to use their heads a little. You are correct about the ID being stored on the questionnaire page, but I figured that it was obvious.

ALL HAIL BRAK!!!
