missing bars

[Katie Ganem]

For some reason when I compile the file I'm working on, bars of music are being 
omitted from the page.  I tried changing the margins, but it didn't seem to 
work.  I then tried inputting more music but it is not even showing up.  I've 
never had this problem with Lilypond before, so I'm not sure if its something 
I'm doing wrong.  But it doesn't come up with an error when I compile it.  

Here is the code I am using.  Attached is a screen shot of what is showing up 
when I compile it.

\book {
\paper {
        left-margin = .75\in
        right-margin = .75\in
  }
}

  title = "Happily Ever After"
}

  \clef treble
