Filter Form Not Working

Using EME 3.3.5 and WP 3.1.3.

The Events page isn’t sorting using filterform, so I tried using GET instead of POST in eme_filters.php (per something on the forums) and it looks like things are starting to happen (the URL field is passing info)

But it’s still not filtering.

Any idea?
