ActionScript 2.0 :: Passing Info From Checkbox To Asp?

how on earth you set about giving a checkbox in a form a varibale.

I'm passing the form to a CDONTS ASP page, and I have three checkboxes, which I need to appear in the retuened email as either blank or 'checked'.

(I have read the tuts here btw - but cannot get them to return a value)

My chk box is called 'chk1'

So my AS on my submit button looks like this:

on (release) {
chk1 = chk1.getSelectedItem().label;
getURL("http://www.holmes.7host.com/promise/mypage.asp", "", "POST");
}

My corresponding ASP page looks like this:

<% @language="VBSCRIPT" %>
<%
Dim myMail, myBody

[Code]....
