Re: [xsl] Doing math in XSLT?

My guess is that you've got the context wrong, i.e. that @namest and @nameend
are not selecting anything because the `<entry>` element isn't the context
item.

It's only a guess, but the code you've shown us is correct, which means the
error must be in the code you haven't shown us, and that makes a context error
a strong candidate.
