Very true. Thank you for the tip. I've cleaned up my code (throughout the entire script), and it's now considerably less gory to read.

However, the problem persists :(

print "Pushing ".$data[$sheet][$iC][$index]." onto holder[$sheet][$iC]
+\n\n\n";

push(@{$holder[$sheet][$iC]}, $data[$sheet][$iC][$index]);

print "holder[$sheet][$iC] = ".$holder[$sheet][$iC]."\n";

Yields

Pushing 1-Jun-97 onto holder[0][3]


holder[0][3] = TTY9.3

Other notes:
@holder is initalized with "my @holder". $holder[$sheet] is initialized with "$holder[$sheet] = ('');" (so that I can reference it in array context and push values.

Anyone know what else may be happening?
