XSL Sheets with a Random number

Hi there,

I am creating a WebPart page in SharePoint that loads a series of announcements and displays one of them at random each time the page loads. So far I have everything setup except for the Random part. Below is a small code snippet where I am having the issues

Code:
<xsl:template name="dvt_1.body">
   <xsl:param name="Rows"/>
   <xsl:for-each select="$Rows[1]" >
       <xsl:call-template name="dvt_1.rowview"/> 
   </xsl:for-each>
</xsl:template>
The above works perfect by loading the first announcement item in the list on displaying it on the WebPart page. If I change this part:
Code:
<xsl:for-each select="$Rows[1]" >
to
Code:
<xsl:for-each select="$Rows[2]" >
as you would expect it displays the second announcement in the list.

What I have tried is to do this
Code:
<xsl:for-each select="$Rows[ddwrt:Random(1, count($Rows))]" >
which by the description of what Random does it should select a number between 1 and the size of Rows (In this case the number of Rows). However what I get is that it just displays all the rows instead of one.

Does anyone know why it is selecting all Rows and not just one or if there is a different tag to be used instead of the for-each one.

Below is the entire style sheet code incase it helps at all.

Code:
<xsl:stylesheet xmlns:x="http://www.w3.org/2001/XMLSchema" xmlns:d="http://schemas.microsoft.com/sharepoint/dsp" version="1.0" exclude-result-prefixes="xsl msxsl ddwrt" xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime" xmlns:asp="http://schemas.microsoft.com/ASPNET/20" xmlns:__designer="http://schemas.microsoft.com/WebParts/v2/DataView/designer" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:SharePoint="Microsoft.SharePoint.WebControls" xmlns:ddwrt2="urn:frontpage:internal">

	</xsl:template>
						<xsl:template name="dvt_1">

		<table border="0" width="100%" cellpadding="2" cellspacing="0">
			<tr valign="top">
				<xsl:if test="$dvt_1_automode = '1'" ddwrt:cf_ignore="1">

				</xsl:if>
				<!-- <th class="ms-vh" nowrap="nowrap">Title</th>

			</tr>
			<xsl:call-template name="dvt_1.body">
				<xsl:with-param name="Rows" select="$Rows"/>
			</xsl:call-template>
		</table>
	</xsl:template>
	
						<xsl:template name="dvt_1.body">
							<xsl:param name="Rows"/>
							<xsl:for-each select="$Rows[1]" >
								<xsl:call-template name="dvt_1.rowview"/> 
								</xsl:for-each>
						</xsl:template>
			
						<xsl:template name="dvt_1.rowview">
		<tr>
		
			<xsl:if test="position() mod 2 = 1">
				<xsl:attribute name="class">ms-alternating</xsl:attribute>
			</xsl:if>
			
			<xsl:if test="$dvt_1_automode = '1'" ddwrt:cf_ignore="1">
				<td class="ms-vb" width="1%" nowrap="nowrap">
					<span ddwrt:amkeyfield="ID" ddwrt:amkeyvalue="ddwrt:EscapeDelims(string(@ID))" ddwrt:ammode="view"></span>
				</td>
			</xsl:if>
			<!--<td class="ms-vb">
				<xsl:value-of select="@Title"/>
			</td> -->
			<td class="ms-vb">
			
			<p><xsl:value-of select="@Title" />
			<xsl:value-of select="@Body" disable-output-escaping="yes"/> </p>
			</td>
			<!--<td class="ms-vb">
				<xsl:value-of select="ddwrt:FormatDate(string(@Modified), 1033, 5)"/>
			</td>-->
		</tr>
	</xsl:template>
</xsl:stylesheet>

Sorry for the messy code, SharePoint Designer is not the best tool to work with sometimes.

Thanks for you help
Tyson
