Drop down menu help please

Hi, just wondering if anyone could help me. I am having trouble saving the selected value. This my javascript code:

<SCRIPT language=JavaScript>
function reload(form){
var val=form.target_proj_no.options[form.target_proj_no.options.selectedIndex].value;
self.location='main.php?target=assign_form_mode&type=p&target_proj_no=' + val ;
}
</script>

And this is some of my php code:

$selected = '';
$target_proj_no = $_GET['target_proj_no'];
$student_q = "SELECT p.proj_no, p.title FROM project p WHERE NOT EXISTS (SELECT * FROM moderated mod WHERE p.proj_no = mod.proj_no) AND EXISTS ( SELECT * FROM supervised s WHERE s.proj_no = p.proj_no) ORDER BY p.proj_no";
$result1 = $db->query($student_q);
if (DB::isError($result1))
	die ($result1->getMessage());

print "<p class=\"bodyheading3\">Assign Moderator to Student</p>";
print "<form method=\"post\">";

print "<p class=\"bodytext\">Project : <select name =\"target_proj_no\"  onchange = \"reload(this.form)\" ><option>-----Select One-----</option>";
while ($result1->fetchInto($row)){
	$proj_no = $row[0];
	$title = stripslashes($row[1]);
	$concat_title = substr($title, 0, 30);
print "<option value=\"$proj_no\" >$proj_no.  " . $concat_title;

}
print "</option></select></p>";

I would be grateful for any help. Thank you.

It's not very helpful to say "i'm having trouble" and then post your code. What sort of trouble are you having? Are you getting an error?

Sorry, The problem I am having is that although the JavaScript and PHP code are working by changing the values of the drop down list when a selection is made, it doesn't save the selected value, but in fact resets the drop down list back to 'select one'.

That's because your javascript function is reloading the entire page:

self.location='main.php?target=assign_form_mode&type=p&target_proj_no=' + val ;

If you want your select box to have a value 'pre selected' when the page loads, you would need to alter the code that generates the select html so it puts 'selected' in the option that you want selected.
