modifying VanWeelden's email button script to not include topic info?

I'm using William Van Weelden's JavaScript to put a button on my WebHelp skin that will open the user's email program (Outlook) and populate with our email address.  We do not need anything in the subject line, CC line, BCC line, or in the Body.  We do not need any of the topic information.  When I try to take out just the references to the topic, either the whole script stops working for the other functions I'm using from his script, or RH freezes.  I'm using RH11 with XP Blue skin, and his JavaScript is in the right place in my Baggage files.  What modification(s) do I need to make?  Thanks, and thanks William

Here's the text of his JS:

function Email() {//Create an email with the link to the current topic.

var url = GetRelTopicURL();
var title = GetTopicTitle();

var emailaddress = "test@example.com";
var message = ""; //Custom message
 
var mail = "mailto:"+emailaddress+"&subject="+title+"&body="+message+"\n"+title+": "+escape(url);

var body = document.getElementsByTagName("body")[0];

var a = document.createElement('a');
  a.setAttribute('href', mail);
  a.setAttribute('style', 'display: none');

body.appendChild(a);
a.click();
