Glad we agree Andy ­ my comments were certainly not aimed at you, but more a
general heads-up for anyone looking at your code, and perhaps for the
original poster to reconsider the empty option approach.

As you say, the value can be left empty, but I find it useful to have a top
option element that has something like ³Please Select² as visible text, with
something similar value. I can then loop through the POST array in PHP
looking for this value in order to catch where the user might have failed to
make a selection. Of course, this simply isn¹t an issue for forms where most
of the fields are optional.

Example code:

foreach($_POST as $key=>$value) {
        if ($value == strtolower("please select")) {
        $errorMsg = "You have neglected to make a selection somewhere.
Please try again.";
        } else {
    // submit data to FM via FX
}
