Change subject line of email when submitting a form using Acrobat X Pro

Question

I have created an interactive PDF in Acrobat X PRO with a submit a form button. Everything works fine all the way through distribution except that I need the Subject Line of the submitted form when attached to an email to read "Form Returned: File Name" rather than "Submitting Completed Form". All of my past forms had the "Form Returned: File Name" subject line automatically...did something change and is it possible to change the subject line? Any help would be much appreciated.

Thank you for your reply. I had actually come across that form on multiple occasions during my research. Looks like I need the doc.mailDoc() function, but there isn't an example of the code. Looking in other places I have tried a few things unsuccessfully. I did find this, which I thought would be even better than Form Returned: File Name in the subject line...actually taking information from fields in the form:
// Build the subject line text from several fields form fields
var subj_text = getField("text1").valueAsString;
subj_text += getField("text2").valueAsString;
subj_text += getField("text3").valueAsString;
// Send the email
mailDoc({
    cTo: "[email protected]",
    cSubject: subj_text,
    cMsg: "Body of email message goes here."
I entered the script(adding in my own information for the email, body and subject line) by adding an action to the button to run the java script but it did not work. Any ideas??
