actionscript - mc.rollOver event listener to sendAndLoad

[daJunkCollector]

I wrote the following script. I have a movieclip named countyA_mc. I want the user to mouse over this movie clip, and result in the sending of a variable to the middle tier.

I can establish communication when I use a .click event listener on a button component, but when I attempt to convert the script (in the following logical way) I do not establish communication with the aspx page:

var hoverColor:Number = 0x9A9A9A;
var originalColor:Number = 0x333399;
var countyTitle:String = "testTitle";
var testingServer:String = "testServer";
 
 
var objectListener:Object = new Object();
objectListener.rollOver = function(ev:Object) {
    var result_lv:LoadVars = new LoadVars();
    result_lv.onLoad = function(success:Boolean) {
        if (success) {
            textArea_ta.text = "Good Day!!";
        } else {
            textArea_ta.text = "Error connecting to server.";
        }
    };
    var send_lv:LoadVars = new LoadVars();
    send_lv.name = title_text.text;
    send_lv.sendAndLoad("destination.aspx", result_lv, "POST");
}
this.countyA_mc.addEventListener("rollOver", objectListener);
