[dancer-users] Trapping parameters from a dynamic list of checkboxes.

[Yitzchak Scott-Thoennes]

The symbolic reference there is $key; you are (unintentionally, I'd

    print FILEHANDLE LIST

syntax, and it is trying to use $key as the filehandle.

Maybe you meant:

    print $key, $input_hash->{ $key }, "\n"
