The solution to this might be so simple that I didn't think about it, but after researching everywhere on this site and google and not finding the answer, I finally decided to post my question.

Here is what I am trying to do. I have a form where I let the user enter an email address and attach a file and on clicking a "Send" button, I want to send out an email using Lotus Notes. Now, I have the "sending an email from Lotus Notes" part figured out. What I can't figure out is how to extract the directory path of the attached file, so I can attach it to the email. I am doing all this using JScript code:

 function CTRL5_5::OnClick(eventObj)
{
        
    var strTo = XDocument.DOM.selectSingleNode("/my:myFields/my:field1").text;
    var strCC ="";
         
    var strBCC = "";
    //var strCC = XDocument.DOM.selectSingleNode("/my:myFields/my:PDRAS_ID").text;
    var strSubject = "PV Info";
    var emailmessage = XDocument.DOM.selectSingleNode("/my:myFields/my:field2").text;
    if(strTo != "")
    {
    sendNotesMail(strTo, strCC, strBCC, strSubject, emailmessage);
    }
    
    //Application.ActiveWindow.Close(true);*/
    
}

function sendNotesMail(strTo, strCC, strBCC, strSubject, emailmessage)
{
    var domSession;
    domSession = new ActiveXObject("Lotus.NotesSession");     
    var domNotesDatabaseMailFile;
    var domNotesDocumentMemo;
    var domNotesRichTextItemBody;    
    domSession.Initialize();
    dbdir = domSession.getDbDirectory("");     
    domNotesDatabaseMailFile = dbdir.openMailDatabase();     
    domNotesDocumentMemo = domNotesDatabaseMailFile.createDocument();
    domNotesDocumentMemo.appendItemValue("Form", "Memo");
    domNotesDocumentMemo.appendItemValue("From", domSession.CommonUserName);
    domNotesDocumentMemo.appendItemValue("SendTo", strTo);    
    domNotesDocumentMemo.appendItemValue("CopyTo", strCC);
    domNotesDocumentMemo.appendItemValue("BlindCopyTo", strBCC);     
    domNotesDocumentMemo.appendItemValue("Subject", strSubject);
    domNotesRichTextItemBody = domNotesDocumentMemo.createRichTextItem("Body");     
    
    domNotesRichTextItemBody.appendText(emailmessage);
    domNotesRichTextItemBody.EmbedObject(1454, "", NEED FILE ATTACHMENT PATH HERE);
    
    domNotesDocumentMemo.Save(true, false);
    domNotesDocumentMemo.Send(false);
    
}

My attachment is at path "my:myFields/my:group1/my:group2/my:field3".

Any help would be greatly appreciated. As I said, the solution could be very simple.
