It's probably not a good idea to make the user's browser hang while you wait for a response from the server.
Have you tried something like this?
$("#summDiv").load("/your/url", {ASXCode:z}, function
(responseText, textStatus) {
// might want to check textStatus here.
doTheChart();
doTheRest(z);
});
Look at the callback parameter here for more info:
