using mailto in actionscript

I've created a banner ad which uses mailto: so when the user clicks anywhere on the banner it opens an email to the customer.

Can I add a subject line?. I tried using the ?subject=xxxxxxx like i would in html, but it threw up errors. Can anyone help?

Also, could I insert some stock content by the same means ie copy in the main body of the message, like "I saw your banner on ..... "

Code:

---

on(release) {
        getURL("mailto:[email protected]?subject=Whatever&body=First Name: %0D%0A Last Name: %0D%0A Telephone: %0D%0A Email Address: %0D%0A Questions or Comments:");
        }

thanks for that, it works a treat.

Anytime !!
