Email Form need to add telephone # to email

Hi,

I am using this email form and it works just fine, but I am trying to figure out how to add additional input feilds that show up in the email body. For example, when you receive the email the body of the email would look like this:
Name:
E-mail:
Telephone:

Feedback:

Below is the AS and the PHP code. Attached is the FLA. Any help would be appreciated

create the LoadVars objects. One for sending information to the php file and one for recieving information.
Although this can be done with one loadvars object, it makes for cleaner code to use two

var sendData_lv:LoadVars = new LoadVars();
var receiveData_lv:LoadVars = new LoadVars();
var formValidated:Boolean;
var errorMessages:Array = new Array();

receiveData_lv.onLoad = function():Void{
    trace(this.sent);
    if(this.sent == "OK"){
     message0_txt.text = "Thank you for your feedback";
    }else{
     message0_txt.text = this.sent;
        }
}


submit_btn.onRelease = function() {
    //this clears the error text field if they have been populate previously
    clearTextFields();
    errorMessages.length = 0; //empty the array so next time the submit button is clicked the array is not already populated
    formValidated = checkForm();
    if (formValidated) {
    //the form is valid and so now we can send details to our PHP file
    //populate LoadVars object with the field values
    sendData_lv.name = name_txt.text;
    sendData_lv.email = email_txt.text;
    sendData_lv.feedback = feedback_txt.text;

    } else {
        //populate textfields with the error messages
        for (var i = 0; i<errorMessages.length; i++) {
             _root["message"+i+"_txt"].text = errorMessages*;
              trace(errorMessages*);
