Change:

<select name="notify_us er_id[4]"

to:

<select name="notify_us er_id[4][]"

Notice the extra [] after the name. So, on the page that processes the
form, you'll have $_GET['notify_user_id '][4] and it will be an array:

foreach($_GET['notify_user_id '][4] as $notify_id) {
//do something with $notify_id
}

Re: Multiple Multiple Select Boxes

Thanks! ...it looks so obvious now.

Final update to the example:

<?php

if (is_array($_GET["notify_user_id "]))
{

foreach($_GET['notify_user_id '] as $id=>$col_val)
{
foreach($_GET['notify_user_id '][$id] as $notify_id)
{
echo "Box=".$id. ", Id=".$notify_id ."<br>";
}
}
}
