Endnote missing?

[John Kane]

I am just playing around with LyX and tried to change a footnote to an endnote 
in a report class document using the commands  
\usepackage{endnotes}
\let\footnote=\endnote

It seems that the endnote disappears.  It works fine in article class.  Any 
suggestions on what I am doing wrong?

On a similar note, can anyone point me to a LyX example where the LaTeX package 
endheads is used?
