Form to post asp

Please Help!
I am trying to create a form in flash for people to subscribe to my emaillist. I got someone to create an .asp for me, I just have to implement the actionscripts on the button in flash to have it talk to it. Nothing is working (but i did get dynamic text to work). I don't know what I am doing (or doing wrong) can somebody help?! I'm using Flash 5.

I've created an "editable text" and variable and a button: I just think I might have the script wrong.

I've tried the Get Url (POST):
on (release) {
getURL ("http://66.242.133.142/jcb/addemail.asp ", "Email", "POST");
}

orLoadVariable:
on (release) {
if (!Email.length || Email.indexOf("@") == -1 || Email.indexOf(".") == -1) {
Message = "Please enter a valid E-mail address";
} else {
loadVariablesNum ("http://66.242.133.142/jcb/addemail.asp", "Email", "POST");
Message = "Thank you for subscribing!";
}
}

Can you see what I am doing wrong?
The text form variable is "Email"
can anyone help?!

please.....
