Variables can't contain '-' char?

Variable named ‘res_file’ works.
Variable named ‘res-file’ fails miserably:

You should definitely try this on 1.3, which is the latest release verson, but the problem here is one of your variables is undefined.

Ansible 1.3 contains a feature to raise a nice error message when one of your variables is undefined.

Variable names should absolutely follow standard variable name conventions, and this is also documented in the pending docs push so other users won’t make the same mistake.

foo-x is not a valid variable name.
