I have a XML structure like:
- - - - 
<EVENTS>
     <EVENT>
            <EYEAR>2007</EYEAR>
            <ENAME>EVENT One</ENAME>
     </EVENT>
     <EVENT>
            <EYEAR>2008</EYEAR>
            <ENAME>EVENT Two</ENAME>
     </EVENT>

</EVENTS>
- - - - 
Then I have a XSL Template with a  for each loop.  Before the for each loop 
I define
a parameter

<xsl:param name="EventYearLast">1999</xsl:param>


<xsl:for-each select="./EVENTS/EVENT">

       I want to do some conditional formatting here based on if the <EYEAR> 
value 
       is different from the previoius <EYEAR> value.   
       something like:

              <xsl:if test="EVENTYEAR != $EventYearLast">
   	    <tr>
                        <td valign="top" colspan="2">
                        <p align="center"><b<u>
                        <xsl:value-of select="EVENTYEAR"/>   
EVENTS</u></b><br/>
	         </p>
                           </td>
	       </tr>		
	</xsl:if> 	

           <xsl:param name="EventYearLast"><xsl:value-of 
select="EVENTYEAR"/></xsl:param>

</xsl:for-each>

The above does not work because it will not allow the <xsl:param inside the 
xsl:for-each  loop

HOW DO IT DO THIS???   I've tried several things to no avail.  There has got 
to be a way.   ????    

Thank you ahead of time!!
