show page numbers in Data View Web Part paging

Question

I'm working on SharePoint 2007. On adding Pagination in the Data View Web Part, by default it shows something like '1-10'. ie the numnber of documents dispalyed. I wish to replace this with exact page number such as '1|2|3|4....' so that the User can directly navigate to any particular Page. I tried to edit the XSLT by following this link: http://blogs.msdn.com/b/cjwalker/archive/2005/05/28/422826.aspx

Steps I followed:

1. Find <xsl:template name="dvt_1.navigation"> and add <xsl:param name="Rows"/> as the last param

2. Somewhere in the that is output in this template

   <tr><td colspan="2" class="ms-vb"> <xsl:for-each select="$Rows"> <xsl:if test="(position() mod $RowLimit) = 1"> <a> <xsl:attribute name="href">javascript: <xsl:value-of xmlns:xsl="http://www.w3.org/1999/XSL/Transform" select="ddwrt:GenFireServerEvent(concat('dvt_firstrow={',position(),'}'))"/>;</xsl:attribute> <xsl:value-of select="((position() - 1) div $RowLimit) + 1"/></a> <xsl:text xmlns:ddwrt="http://schemas.microsoft.com/WebParts/v2/DataView/runtime" ddwrt:nbsp-preserve="yes" disable-output-escaping="yes">&amp;nbsp;</xsl:text> </xsl:if> </xsl:for-each> </td></tr>

3. Find <xsl:call-template name="dvt_1.navigation"> and add <xsl:with-param name="Rows" select="$Rows"/> as the last param.

I followed exact steps but but it shows error that the webpart cant be rendered. Can any body tell me whats missing in this code.

Thanks in Advance
