In the real code, U have a variable where the file names are. I
replaced that with actual file names to avoid any confusion. I guess
in the process I messed up the quotes.
In any case, I opened up the downloaded file in a binary editor and
found that the entire HEAD section is added upfront (names of style
sheets, description, etc.). How do I prevent this from happening?
