Menu from MySQL

I am trying to automate menu creation, I'm still somewhat new at this, I managed to get a navigation system to work, (index.php?sectionid=xx&pageid=xx). I'm pretty sure I have no idea here and am completely off but here goes...

<?php
$G1 = mysql_query('SELECT * FROM section WHERE category = 1');
$G2 = mysql_query('SELECT * FROM section WHERE category = 2');
$GRAB = mysql_query('SELECT * FROM nav WHERE sectionid = "'. $sectid. '"');
?>

<div id="leftnav">
<?php

while($nav = mysql_fetch_array($G1)) {
$sectid = $nav['sectionid'];
$titlea = $nav['title'];
echo '<div class="box"><div class="boxtitle">'. $titlea .'</div><ul>';
while($nava = mysql_fetch_array($GRAB)) {
echo '<li><a href="#">'. $nava['name'] .'</a></li>';
}
echo '</ul></div>';
}


?>
</div>

<div id="rightnav">
<?php

while($nav = mysql_fetch_array($G2)) {
$sectid=$nav['sectionid'];
$titlea = $nav['title'];
echo '<div class="box"><div class="boxtitle">'. $titlea .'</div><ul>';
while($nava = mysql_fetch_array($GRAB)) {
echo '<li><a href="#">'. $nava['name'] .'</a></li>';
}
echo '</ul></div>';
}


?>
</div>


I got all the boxtitles and boxes to show up, but the list items do not :| Database is simple now, until I get it to work...
table 'section' has 3 columns: "category", "sectionid", "title"
table 'nav' has 2 columns: "sectionid" & "name"

I am trying to implement this completely wrong?

$GRAB = mysql_query('SELECT * FROM nav WHERE sectionid = "'. $sectid. '"');

this line at top sectid is not set till futher down really needs to be

in while loop which starts around line 28


while($nav = mysql_fetch_array($G2)) {
$sectid=$nav['id'];
$GRAB = mysql_query('SELECT * FROM test WHERE id = "'. $sectid. '"');

Dynamic Menus are the way to go! Here's a Menu Class I put together and have been using for a long time. Hope someone finds it useful.
