# \lyxframeend Undefined when Using Beamer with Lyx

I’m using LyX for the first time with Beamer. Making the title page was smooth. But when I’ve tried adding a new frame (using BeginFrame) I was confronted with the following error

 \lyxframeend
{}\lyxframe{Outline}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), type I' and the correct
spelling (e.g., I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.`

After comparing my document to example (working) beamer documents I’ve found out that you must have an EndFrame command after your last frame. Too bad it wasn’t documented anywhere I’ve found as this little thing drove me crazy.
