Hi,
With some help I’ve almost solved the updating problem
MAINTIMELINE Frame 1:


this.regForm_mc.onData=function(){
	//DATA FINISHED LOADING.
	//LET'S DISPLAY IT!
	this.play();
	
	
	
}

INSIDE regForm_mc frame (1)


// Don't play movie clip initially
stop();
//
function valForm() {
	//Form Validation
	// Make sure the user filled in all the required fields.
	if (!name_txt.text.length || name_txt.text == " ") {
		status_txt.text = "All fields are required";
	} else if (!email_txt.text.length || email_txt.text == " ") {
		status_txt.text = "All fields are required";
	} else if (!location_txt.text.length || location_txt.text == " ") {
		status_txt.text = "All fields are required";
	} else {
		status_txt.text = "";
		//Define TextFields
		//Name = name_txt.text;
		//Email = email_txt.text;
		//Location = location_txt.text;
		// loadVars object
		// loads specific variables and sends them
		myVars = new LoadVars();
		myVars.name = name_txt.text;
		myVars.email = Email_txt.text;
		myVars.list = list_txt.text;
		myVars.location = location_txt.text;
		trace(myVars.toString());
		//
		myVars.sendAndLoad("register.php", myVars, "POST");
		//
		//
		// Display the loading frame while data loads.
		gotoAndStop("Loading");
	}
}
submit_btn.onRelease = valForm;
