Right now, the sum shown on the page is the sum of the price for ALL plants 
that cost less than $9.00. How do I use sum() to display the sum only for 
the plants displayed in the chart (i.e. all zone 4 plants that cost less 
than $9.00)? I've tried several approaches, but they don't work.


Something like

sum(/CATALOG/PLANT[GROWTH/ZONE=4 and SALESINFO/PRICE &lt; 9])
