My first guess was that $key is undef. But I'll get back to that...

The respondant who said that either $SERVER{$key}{one} or $SERVER{$key}{two} is undef was wrong. The one who said that printing "0" instead of the empty string meant that neither of those is undef is correct.

But my first guess is also wrong because you didn't get the warning from the print statement. So my final guess is that one of the else or one of the elsifs associated with that if is really where the warning is coming from.

For some reason, Perl often (always?) reports errors in the else and elsifs as if they came from within the if. I used to think that this was due to an optimization trick but that trick was only done in Perl 4.
