You've scoped @node_numbers local to the blocks of the if. The @node_numbers you're using outside those blocks is not the same variable (it's a global -- you should use strict;).

Once you fix that, if you run it from the command line, it's going to try to get data from STDIN, which will generally be the keyboard. You'll get the error-out if you redirect from /dev/null.

Caution: Contents may have been coded under pressure.
