Re: How can I solve this Global Variable Problem here

You don't need a global variable at all.

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                version="1.0">

<xsl:template match="/">
  <xsl:apply-templates />
</xsl:template>

<!-- you don't need those other templates - applying templates
  to all elements is the default behaviour -->

  <xsl:template match="WeekDay">
    <xsl:value-of select="//WeekDayName/WeekName[
        @name = string(current()/text())]" />
    <xsl:text>&#xA;</xsl:text> <!-- carriage return -->
  </xsl:template>
</xsl:stylesheet>

This isn't tested, and may not work on IE5, though it should
work with any conforming processor.
