Hi Sam:

It makes sense that you are getting a bunch of errors telling you the object
doesn't exist, because the JScript engine is looking for objects named, for
example, in the case of the filter function, the actual given name. But you
have no id attribute assigned to the object, so the JScript processor can't
find the object. So, as just one example, do this:

<xsl:attribute name="id"><xsl:value-of select="@givenName"/></xsl:attribute>

I added this to your SortByTemplate template, and the JScript engine was
able to find the object and display the information okay. So, this is what
the beginning of that template now looks like (I added a cursor style
because it drives me crazy to see an onclick event with no hand cursor
associated with the event source):

<xsl:template name="SortByChoice">
  <TR bgcolor="#FAEBD7">
   <TD><font face="Verdana" size="1" color="black"><xsl:value-of
select="@sn"/></font></TD>
   <TD><font face="Verdana" size="1" color="black"><xsl:attribute
name="onclick">filter('<xsl:value-of select="@givenName"
/>');</xsl:attribute><xsl:attribute
name="style">cursor:hand;</xsl:attribute><xsl:attribute
name="id"><xsl:value-of
select="@givenName"/></xsl:attribute><u><xsl:value-of
select="@givenName"/></u></font></TD>
...

The only change is the additional xsl:attribute that creates an id
attribute. You could also have used attribute value templates, they're a bit
cleaner in my view, but this will work. You'll need to follow this procedure
whererever you have function calls.
