Script needed

To email a form I use the script below:

var myDoc = event.target;
var address = "xxx [at] xxx [dot] org";
var sub = "Photocopying Requisition Form_";
var msgBody = "See my Photocopying Requisition Form attached.\n\nThank You!";
var Sender = form1.SubALL.Sub_1.Req_Name.rawValue;

myDoc.mailDoc({ bUI: false,
cTo: address,
cSubject: sub,
cMsg: msgBody + "\n\nRegards\n" + Sender,
cSubmitAs: "PDF"});

It's work fine! Just I will like to make a addition.
Is it possible on the subject line to have also(Plus) the select Item(No the Value) of a Drop Down List?
The script above gives me only: Photocopying Requisition Form_

Thanks for your help
