Adobe Acrobat Pro Submit a pdf to a user generated email?

Question

Using Adobe Acrobat Pro I am filling out a form that will be used by a variety of people, each with their own team lead. I want people to be able to fill out the form, type in the email of their team lead, and then have a submit button that will submit the form to that email.

Does anyone know what javascript I need to write to accomplish this?

I tried the Submit form function of the adobe acrobat button, but it doesn't allow me to customize the Mailto: form.

Edit: I found Javascript that lets users fill in a text entry field that will then be the subject of the body once the users click the submit button. Can someone who is more savvy than I rework this so that the email address is the one based on the user's entry?

Where "MyTextField" is the earlier user text field for the subject:

var customSubject = this.getField("MyTextField").value;
var mailtoUrl = "mailto:[email protected]?subject=" + customSubject;
this.submitForm({
 cURL: mailtoUrl, bPDF:true
});

I'm trying to learn a bit about code as I look through this. Why would this workaround not work?

var customSubject = Tomato;
var mailtoUrl = "mailto:this.getField("MyTextField").value?subject=" + customSubject;
this.submitForm({
 cURL: mailtoUrl, bPDF:true
});
