how do you redefine a variable

I'm trying to colour my table rows, either one colour or another.

I thought I'd do something similar to how I do it ASP.

<xsl:variable name="rowCounter">1</xsl:variable>
<xsl:for-each select="">
  <xsl:choose>
    <xsl:when test="$rowCounter = 1">
      <xsl:variable name="bgcolor">red</xsl:variable>
      <xsl:variable name="rowCounter">0</xsl:variable>
    </xsl:when>
    <xsl:otherwise>
      <xsl:variable name="bgcolor">blue</xsl:variable>
      <xsl:variable name="rowCounter">1</xsl:variable>
    </xsl:otherwise>
  </xsl:choose>
</xsl:for-each>

BUT, it won't let me reallocate $rowCounter as it's already defined. So, how
could I do this using the wonders of XSL. I thought about getting the
position() value, and doing something with this, but it would ultimately
need to be a 0 or 1 (or 1 or 2 if that's easier). Is there an If
odd(position()), if even(position()) syntax I could use?

Thanks for now.....

Daniel.
