Hi Guys,

I have been following some videos on Umbraco TV by Worren, just to get a simple Umbraco Site up and running. I am attempting to create a Dynamic Navigation using Worrens XSLT. When I try and save the script I get the following Error.

Error occured

System.OverflowException: Value was either too large or too small for an Int32.
at System.Convert.ToInt32(Double value)

at umbraco.presentation.webservices.codeEditorSave.SaveXslt(String fileName, String oldName, String fileContents, Boolean ignoreDebugging)

Does anyone have any idea what this is refering to? I'm new to XSLT but under stand it is refuring to a Number that is too big or too small but I can't figure out which part is wrong.

Here is the XSLT File:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [
    <!ENTITY nbsp "&#x00A0;">
]>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:msxml="urn:schemas-microsoft-com:xslt"
  xmlns:umbraco.library="urn:umbraco.library"
  exclude-result-prefixes="msxml umbraco.library">
 
  <xsl:output method="xml" omit-xml-declaration="yes"/>
  <xsl:param name="currentPage"/>
 
  <xsl:template match="/">
 
    <!-- Root Node -->
    <xsl:variable name="rootNode" select="$currentPage/ancestor-or-self::root" />

    <!-- Homepage -->
    <xsl:variable name="homeNode" select="$rootNode/Home [@isDoc]" />
   
    <ul id="navi">
      <li>
        <!--
        Add the CSS class 'selected' if the homeNode ID matches our
        currentPage node ID
        -->
        <xsl:if test="$homeNode/@id = $currentPage/@id">
          <xsl:attribute name="class">
            <xsl:text>selected</xsl:text>
          </xsl:attribute>
        </xsl:if>
       
        <!--Create a link to the homepage -->
        <a href="{umbraco.library:NiceUrl($homeNode/@id)}">
          <xsl:value-of select="$homeNode/@nodeName" />
        </a>
      </li>
     
      <!--
      For each child node of the homeNode that is a document (isDoc)
      and the level is 2
      and the property umbracoNaviHide is NOT 1 (true/checked)
      -->
      <xsl:for-each select="$homeNode/* [@isDoc and @level = 2 and string(umbracoNaviHide) != '1']">
        <li>
          <!--
          Add the CSS class 'selected' if the currentPage or parent nodes (up the tree to the root)
          ID matches our current node's ID in the for each loop
          -->
          <xsl:if test="$currentPage/ancestor-or-self::* [@isDoc]/@id = current()/@id">
            <xsl:attribute name="class">
              <xsl:text>selected</xsl:text>
            </xsl:attribute>
          </xsl:if>
         
          <!-- Create the link -->
          <a href="{umbraco.library:NiceUrl(@id)}">
            <xsl:value-of select="@nodeName" />
          </a>
        </li>
      </xsl:for-each>
    </ul>
  </xsl:template>
</xsl:stylesheet>

I'm running the following;

Microsoft Windows Server 2003 R2 x64
Microsoft .NET 4.0
SQL CE
Umbraco 4.6.1

Any help or any pointer on how to fix this then I would be thank full.
