From perldiag: Argument "%s" isn't numeric%s

(W) The indicated string was fed as an argument to an operator that expected a numeric value instead. If you're fortunate the message will identify which operator was so unfortunate.

This means although the warning is displayed your program should run normally.

Correct. Warning. Sorry. However it still prints a zero in the spots that I want blank.

Hmm, now i reached the end of science (at least to my knowledge) so let's start with the voodoo (aka blind guessing):
• I know there's an int($foo) function that returns the integer part of a variable. Maybe there is something similar for strings?
• Have u tried to use another character instead of a blank? something like - or . ?
As I said both is just vlind guessing and will propably not work. Your program seems to think that right at this place there has to be a number. I don't know why it does this, but maybe some other monk can bring some clarification to this?

Correct, I'll rephrase that to Warning, and continue to comment that it still does not suppress zero values.
