Globalize doesn't check it, just forces it as that. So if the integer is an A, it will be set as 0.

For making it required, you could do a a check like:

PHP Code:

if (empty($_REQUEST['eggnog']))
{
    $errormessage = "Invalid brand of eggnog specified.";
    eval('print_output("' . fetch_template('STANDARD_ERROR') . '");');
}
