I have a Beamer file that starts




\title{I'm disabled, I'm also abled}
\author{Peter L. Flom}



I am getting errors

    Runaway argument?
\let \AtEndDocument \@firstofone \@enddocumenthook \@checkend {docume\ETC.
! File ended while scanning use of \beamer@collect@@body.
<inserted text> 
<*> Fall2014.tex

I have no idea what this means.

I tried commenting out most of the preamble, but still got errors.

    Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem.

    With that error message, I'd guess you've forgotten an } somewhere :-)

    One comment: there is no need to call \usepackage{graphicx} with beamer, as it already provides this functionality. May 10, 2016 at 21:50

1 Answer 1


I solved the problem. It was a missing \end{frame} much later in the document.

I think that this error is sufficiently opaque that some documentation that this is one possible reason for it should be on the web somewhere, and no better place than here.

But if the moderators disagree, I will delete the post

Thanks for the help

    As this answer points out, "It's actually not uncommon to end up finding the solution yourself when you start trying to construct a minimal example". It seems like you experienced that now. If anything, your experience just highlights the importance of constructing a minimal example.
