customization layer not working?

[Webmaster <Webmaster@comtrol.com>]

Hello.

I wrote a customeization layer my application, and rewrote the 

<xsl:template match="productname" mode="titlepage.mode">

template in my customerization.xsl. However, it's not overriding the one
found in html/titlepage.xsl.

If I remove the one found in html/titlepage.xsl, mine works just fine.  I'd
rather not change the original stylesheet files. 

Am I missing something?  I thought the "last" template found, wins?
