Hi Jeni,

I'm curious about your solution:

>       <xsl:otherwise>0</xsl:otherwise>
>     </xsl:choose>
>   </xsl:variable>
>   <xsl:variable name="n2">
>     <xsl:choose>
>       <xsl:when test="number($t2) = number($t2)">
>         <xsl:value-of select="$t2" />
>       </xsl:when>
>       <xsl:otherwise>0</xsl:otherwise>
>     </xsl:choose>
>   </xsl:variable>
>   <xsl:variable name="temp1" select="$n1 + $n2" />

I have the understanding that the XPath number() function will return the string 'NaN' if the parameter passed in is not a number. Though, at a lower level, won't the same function called twice with identical parameter(s) return the same thing? So, when would your test of "number($t1) = number($t1)" fail?

Confusedly,
Joshua
