This is pretty much what I've been looking for...

Something seemed redundant, and I assumed it to be %departments, but you're right; @classes is not really needed.

And ++ on the sort. I forgot to sort my keys, since it showed up fine when I was testing, but that was due too a not large enough dataset :-)

Thanks.

Not that it means anything of course, since any improvement I get here means a speed increase of thousandths of a second (guessing), but I was curious....
