Hi,

A couple of points: I'm not sure if they'll help with the immediate problem,
though!

1. I don't think the upload case ever calls a failure handler - they all go to
upload (check http://developer.yahoo.com/yui/connection/#upload)
2. It's not clear if you're using an SSL connection, but if so you'll need the
third argument in setForm set to true:
var postData = YAHOO.util.Connect.setForm(f, true, true);
3. test for undefined using ===, rather than ==
4. o.responseText should be what's in the iframe that's used for the upload (see
the docs linked above), but I'm not sure of the detail of this. Is the filesize
enforcement at the form or server? That may affect things. What does your
server return if the file is too big?

Hope that's helpful, but may not be!

Matt
