 Hi John, The syntax you have written is a valid XSLT syntax. But it does not calculate correctly the average of last 20 (varDays) <cl> (within <day>) elements. My XSL relies on nodeset extension function. If you are using Xalan, you can use my code as it is, otherwise you have to use your XSLT processor's nodeset syntax.
