I just tried it and the entryfield event seems to be aware of the form.rowset object, so I guess that option 1 (and akshat's option) should work, but I was confused as to why it does work... So I went to Ken's books and I think I found the answer... anything instantiated with (this) in a form and its event handlers, e.g. this.entryfield1 = new entryfield(this) and entryfield1's onchange event would know what "form.rowset" is. Does that sound right, Ken? Gaetano.
