mailto: using a parameter on the adobe form.

I'm wanting to use a submit form with a mailto: function that will mail the form to the email address in a email text box on the form. Everything I have seen uses hard coded email addresses.

mailto:myemail@hotmail.com?cc=myemail@yahoo.com
I want to
mailto:"value in email text box 1"?cc= "value in email text box 2"

Thanks in advance.
