Change font size of contact form.

Question

Hi,
I have been searching through google and various forums to make a contact form, and I finally have it working. (YAY!) HOWEVER...
There's one problem: I don't know how to change the font size. Help?!
Here's my action script code:
submit_btn.addEventListener(MouseEvent.CLICK, sendMessage);
function sendMessage(e:MouseEvent):void{
var my_vars:URLVariables = new URLVariables();
my_vars.senderName = name_txt.text;
my_vars.senderEmail = email_txt.text;
my_vars.senderMsg = message_txt.text;
var my_url:URLRequest = new URLRequest("http://mydomain.com/mail.php");
my_url.method = URLRequestMethod.POST;
my_url.data = my_vars;
var my_loader:URLLoader = new URLLoader();
my_loader.dataFormat = URLLoaderDataFormat.VARIABLES;
my_loader.load(my_url);
name_txt.text = "";
email_txt.text = "";
message_txt.text = "Message Sent";
Do I need to add something to my action script to modify the text size? If so, what? Or do I modify the text size through other means? I've been looking at tutorials online, forums, and I just couldn't find something that helped me.
Thank you!

Ahh. Thanks for being patient with a newbie.
So I've got the code in and compiler errors came up:
Scene 1, Layer 'content', Frame 70, Line 3
1119: Access of possibly undefined property defaultTextFormat through a reference with static type fl.controls:TextInput.
Scene 1, Layer 'content', Frame 70, Line 4
1119: Access of possibly undefined property defaultTextFormat through a reference with static type fl.controls:TextInput.
Scene 1, Layer 'content', Frame 70, Line 5
1119: Access of possibly undefined property defaultTextFormat through a reference with static type fl.controls:TextArea.
Below is what I have in action script, did I need to place the code you gave me somewhere else?:
var tfor:TextFormat=new TextFormat();
tfor.size=12;
name_txt.defaultTextFormat=tfor;
email_txt.defaultTextFormat=tfor;
message_txt.defaultTextFormat=tfor;
submit_btn.addEventListener(MouseEvent.CLICK, sendMessage);
function sendMessage(e:MouseEvent):void{
var my_vars:URLVariables = new URLVariables();
my_vars.senderName = name_txt.text;
my_vars.senderEmail = email_txt.text;
my_vars.senderMsg = message_txt.text;
var my_url:URLRequest = new URLRequest("http://mydomain.com/mail.php");
my_url.method = URLRequestMethod.POST;
my_url.data = my_vars;
var my_loader:URLLoader = new URLLoader();
my_loader.dataFormat = URLLoaderDataFormat.VARIABLES;
my_loader.load(my_url);
name_txt.text = "";
email_txt.text = "";
message_txt.text = "Message Sent";
