Assisting: both errors appear to refer to a lack of content in $_ the default variable set by various operations. $_ is explicitly mentioned in your line 3 and implicit in your line 2. Inserting a print $_\n before the chomp will probably confirm or rebut my hypothesis. Then, if I'm on target, you can read up to find what you expected to set the default.
