Answer 1

Apparently, your event.target.data.return_msg or event.target.data.choice1Count etc variables are empty (null).
First check if your PHP script is echoing a correct response ($my_msg or $choice1Count might be null there as well). If the PHP script is fine, try to trace these values in your completeHandler method:
trace("message : " + event.target.data.return_msg);
trace("choice1Count : " + event.target.data.choice1Count);
