NaN

[u]XSLT: Version 1.0
[u]Platform: Windows XP

[u]XML:
<Charge Id="77" Amount="139.97" CurrCode="EUR" Type="5" PT="P"/>
<SAPCreditItem CreditDate="20080520" CreditAmount=""/>

[u]XSL:
<xsl:variable name="total" select="Charge[@Id='77' and @Type='5' and @PT='P']/@Amount + SAPCreditItem/@CreditAmount"/>

[u]Result: <xsl:value-of select="$total"/>

I tried with, <xsl:variable name="total" select="Charge[@Id='77' and @Type='5' and @PT='P']/@Amount[number()=number()] + SAPCreditItem/@CreditAmount[number()=number()]"/>...But again the output is Nan.

How to avoid NaN. When the value is empty( CreditAmount="" ) as shown above.

[u]Expected result: 139.97
[u]Actual result: NaN

Code:

sum(Charge/@Amount | SAPCreditItem/@CreditAmount[.!=''])

Please don't ask the same question on several forums at the same time. It's reasonable to ask one one forum if another one fails to come up with the answer, but to use several at once is bad etiquette - it's like ordering free drinks from more than one barman and then leaving one of them untouched.
