forms - mail arrive without the file php

Next page works, but I do not get the file with the mail when submit.

The mail that arrives:

MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="==Multipart_Boundary_xa18882382b8d92109533240902ace32ex"

--==Multipart_Boundary_xa18882382b8d92109533240902ace32ex Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit

...and after thet ther is the valius from the inputs ( $msg)

... then

--==Multipart_Boundary_xa18882382b8d92109533240902ace32ex

What's wrong? Why I'm not getting the file if I do not get any php warning from the page?
