thank you so much. I was a bit confused at the beginning: I thought that you had to specify a starting value for $hoh{$c1}{$c2}{count}. By the way, and I know I'm going a bit astray of the initial question, but what if I wanted to start that count at 5? Would specifying

$hoh{$c1}{count}=5;

work if I specified it before incrementing in your while loop? Thanks!
