How to get "Subject" & "Message" text from Flash form to default e-mail MS Outlook?

Hi,

I have the following code which is working fine except I can't get the user typed data from flash form to my default e-mail (MS Outlook) application. How to edit the following code?

In the code:

1) To  ---->  this field is okay since this email ID doesn't change

2) Cc  ---->  this filed is also okay since no changes will be in email ID

3) Subject  ----> this may not be always as "Feedback", user may like to change the subject

Whant I would like to add more here is:

1) From  ----> this text to be retrieved from "fromText.txt" input text box

2) Message  ----> this text to be retrieved from "MessageText.txt" input text box

//1.Button event listener
SendMail.addEventListener(MouseEvent.CLICK, SendEMail);

//2.The SendMail function open up email application to send email.

function SendEMail(event:MouseEvent):void {
var email:URLRequest = new URLRequest("mailto:administrator@helpdesk.com?CC=poweruser@helpdesk.com&Subject=Feedback");
navigateToURL(email, "_blank");
}

Thanks in advance for any support.

Regards.
