Error in compairison of variables (possibly type)

[thewade <pdman@xxxxxxxxxxxxxxxx>]

Greetings,

I recently downloaded and installed your mod_xslt software and was  
quite pleased with the ease of installation and configuration.

I think I found a bug though, that I hope you can help me with.

The value-of always returns false in the case below:
(position in this case goes from 1 to 10)

   <xsl:variable name="this_show" value="position() * 2 - 1"/>
   <xsl:variable name="half_shows" value="ceiling(last() div 2)"/>
   <xsl:value-of select="$this_show &lt;= $half_shows"/>

But if I do below I get true half the time and false the other half:

   <xsl:value-of select="position() * 2 - 1 &lt;= ceiling(last() div 2)"/>

The problem is stopping me because I am trying to call items like this:

   <xsl:value-of select="../show[$this_show]/venue"/>

The above returns nothing ever, but if I do this:

   <xsl:value-of select="../show[1]/venue"/>

I get the venue for the first show.

It seems like the variables $var are being treated as strings - that  
is the only thing I can think of that would cause this problem.

Can you lend me a hand?

Thanks,
