I have aworking copy of this here: [url]http://www.childsinc.com/rss
however, i have changed that page to use GET instead of POST since bokeh told me i was wrong to use POSt this way. another difference in this script is that i moved the DB work into a function but i can’t seems to figure out why the array returned has only the last element in the DB.
