Hi,
Thanks Georg Baum,
I had added it to the preamble section and it works. I had try before to add it to the document (\usepackage{cancel}) with C - l and it didnt work. Now i know why.
I had use Uwe document at: http://wiki.lyx.org/pmwiki.php/LyX/LyXMathebefehle
to learn how to control the arrow in \cancelto

Hi to all,
I am having problem using in the math mode the options in cancel.sty
When i write in math mode: \cancel{, its write the word cancel in a black color and near it place {}. You could write between the two baraks.
It should occur in red. Maybe you are writing it inside a text box in mathmode? What happens if you create a fesh math box with C-m and then write \cancel{?
My problem is that i receive the following error:
Undefined control sequence. \L{$\cancel
Did you load the cancel package with
\usepackage{cancel}
in the preamble?
Georg
