I developed an importer to move members from one site (none umbraco) to a new one. I had an xslt file that was displaying information correctly until after imported all the new members. now i cant get the member properties to display correctly:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xsl:stylesheet [ <!ENTITY nbsp "&#x00A0;"> ]>
<xsl:stylesheet 
    version="1.0"

<xsl:output method="xml" omit-xml-declaration="yes"/>

<xsl:param name="currentPage"/>

  <xsl:template match="/">

    <xsl:choose>
      <xsl:when test="umbraco.library:RequestQueryString('memberId')">
        <xsl:variable name="mxml" select="umbraco.library:GetMember(umbraco.library:RequestQueryString('memberId'))" />

        <xsl:call-template name="details">
          <xsl:with-param name="mxml" select="$mxml" />
        </xsl:call-template>
      </xsl:when>

      <xsl:otherwise>
        <xsl:variable name="mxml" select="umbraco.library:GetCurrentMember()" />

        <xsl:call-template name="details">
          <xsl:with-param name="mxml" select="$mxml" />
        </xsl:call-template>
      </xsl:otherwise>
    </xsl:choose>


</xsl:template>


  <xsl:template name="details">
    <xsl:param name="mxml" />

    <h2>
      <xsl:value-of select="$mxml"/></h2>
    <div class="usercolltop">
      <div>
        <div style ="float:left; width:120px;height:120px;margin-right:10px;" >
          <img  src="{$mxml/profilePicture}" onerror="ImgError(this);" width="120" height="120" />
        </div>
        <br/>
      </div>

      <div>

        <h3>
          Name: <xsl:value-of select="$mxml/firstName"/>&nbsp;<xsl:value-of select="$mxml/lastName"/>
        </h3>
        <h3>
          Email: <xsl:value-of select="$mxml/myEmail"/>
        </h3>
        <h3>
          Address: <xsl:value-of select="$mxml/address"/>
        </h3>
        <input type="button" id="btnEditMyProfile" value="Edit My Profile" />
      </div>
    </div>
    <br/>

  </xsl:template>  


</xsl:stylesheet>

this line:    <h2>

<xsl:value-of select="$mxml"/></h2>

is displaying the member and all the properties as you would expect. but then these lines:

          Name: <xsl:value-of select="$mxml/firstName"/>&nbsp;<xsl:value-of select="$mxml/lastName"/>
        </h3>
        <h3>
          Email: <xsl:value-of select="$mxml/myEmail"/>
        </h3>
        <h3>
          Address: <xsl:value-of select="$mxml/address"/>

are displaying absolutely nothing...
