Hi Michel,

I made some modifications on your original Xsl (took the ss namespace out) that ended up messing your template. Sorry about that!

Here is the same piece of code adapted to your original scenario:

<xsl:when test="string(number(.))!='NaN'">
	<Data ss:Type="Number">
		<xsl:value-of select="."/>
	</Data>
</xsl:when>
<xsl:otherwise>
	<Data ss:Type="String">
		<xsl:if test="(.) != 'NULL'">
			<xsl:value-of select="."/>
		</xsl:if>
	</Data>
</xsl:otherwise>

Please let me know if it works.
