Add a phpinfo() at the end of your page. In the output you
can see the HTTP_POST_VARS etc. and the format in which they
are passed to your script.
Or try print_r($frm) to inquire your array.

I do not understand the need of the nested loops, isn't it
this what you want to do?

$glearray = $frm["glenum"];
foreach ($glearray as $val) {
    $qid = db_query("INSERT INTO lesson_gle (l_id, glenum)
                           VALUES ('$id', '$val')");
}
