Thanks, Dan!

thanks a lot for your help!
I have already made a lot of progress. Title and authors work well. I also managed to truncate the title after certain chars and select only the authors (not the editors).
I still have, however, some problems with the date. I do get it but it is formatted in very different ways. Sometimes it is just the year (which I want), sometime it is something like "2007-05-19", and sometimes it is "October 2007". Do you know whether it is possible to get only the year? I guess I would be able to write some code which allows me to extract the year from the different formats. But this is not very elegant and might cause problems if the date is formatted in a unexpected way.

Thanks again,
Greg

ps: I will try to add an attachment later when I have done the other stuff…

I'll write a more thorough answer later, but try the following:

// get Zotero, ZoteroPane
var Zotero = chromeWindow.Zotero;
var ZoteroPane = chromeWindow.ZoteroPane;

//get first selected item and output its title
var items = ZoteroPane.getSelectedItems();
var item = items[0];
output ('title: ' + item.getField('title'));

// creators — get the first creator's last name
var creators = item.getCreators();
creators[0].lastName;

// date

var date = item.getField('date');
date;

// attach file
// see http://groups.google.com/group/zotero-dev/browse_thread/thread/319c69f7882fe171#

var fileName = 'D:\\Document\\Zotero\\chickenfoot\\greg.answers.js'
var file = Components.classes["@mozilla.org/file/local;1"].
createInstance(Components.interfaces.nsILocalFile);
file.initWithPath(fileName);

Zotero.Attachments.linkFromFile(file, item.id);

Thanks!!!
