Hi, ChartMan and looked at your code, and there are several problems there:
1. Don't call setOnLoadCallback twice. 2. setQuery() accepts an SQL-like syntax (see http://code.google.com/apis/visualization/documentation/querylanguage.html), so send it "select sales", not "sales". 3. The reqId returned from the data source should match the reqId sent with the request. For example, enter " http://site2.dev.workcircle.net:81/php/sales.php"; and you'll see that the response has 'reqId:1' even though the request had no reqId which means reqId:0.
