How to validate a multiple drop down list in php?

Hi,

I'm trying to figure out a way to propertly validate a mulitple drop down list in php. My below syntax produces a 404 error when I press the "submit" button. What am I doing wrong?

Thanks

PHP Syntax

$month          = $_POST['month'];
$day            = $_POST['day'];

if(isset($month) && $month === '0'){
    $birthdayNumberError = __('<span STYLE="font-size: x-medium; color: #000000">Birthday works, I think</span>' ,'language');
    $error_message .= 'Enter a valid Month\n';
    $hasError = true;
} else if (isset($day) && $day === '0' && isset($month) && $month === '0'){
    $birthdayNumberError = __('<span STYLE="font-size: x-medium; color: #000000">Birthday works - Day, I think - Else Statement</span>' ,'language');
    $error_message .= 'Enter a valid Month\n';
    $hasError = true;
}

HTML Syntax

<li>
<label for="birthday">
<?php _e('Birthday:','language');?>
