Drop down option box not displaying items

[vanessia_1999]

I am having trouble displaying the item listed in my drop box. It is not showing up anything. The list is blank. I don't know what the problem is. At first I thought it was because of an undefine varialbe, but thanks to Keith help with the undefine variable issue, I learned that was not the reason my list is not displaying.

May someone please help me solve this headache.
thanks

incorrect code - will repost

[vanessia_1999]

would a foreach loop not be a better option?

<?php
    $sql = "SELECT p.description, c.item_color, cp.attributeid FROM products p, color_list_attribute cp, color_list c WHERE cp.prodid = p.prodid AND cp.colorid = c.colorid ORDER BY p.description";

    $result = mysql_query($sql);

    echo "<h2>Product Color Associations</h2>";
    echo "<table><tr><td>Product</td><td>Color</td><td>&nbsp;</td></tr>";

    foreach($rows as $row) {

	echo "<tr><td>".$row['description']."</td><td>".$row['item_color']."</td><td><form action=\"?content=colors\" method=\"post\"><input type=\"hidden\" name=\"attid\" value=\"".$row['attributeid']."\"><input type=\"submit\" name=\"submit\" value=\"Delete\"></form></td></tr>";


    }

    echo "</table>";
?>

i change all the single quotes to double quotes to double quotes as i have had issues in the past and diong it the hard way sometimes just works.

Thanks Leviathan, but thats not the problem. I do thank you for trying though. I am going to make the code shorter where the problem exactly is.

<?php
// manage colors

if(isset($_POST['submit']) && isset($_POST['attid'])){
    $q = 'DELETE FROM color_list_attribute WHERE attributeid='.$_POST['attid'];
    $r = mysql_query($q);
    if($r !== false) echo '<h2>Color Product Association removed.</h2><br><br><br>';
}
// Add new color
if(isset($_POST['submit']) && isset($_POST['color'])){
    $r =mysql_query('INSERT INTO color_list VALUES ("","'.$_POST['color'].'")');
    if($r !== false) echo '<h2>New Color Added</h2><br><br><br>';
}

Instead of <?=$prod_options;?> try <?php echo $prod_options; ?>

Thank you Keith, you are a life saver. I been tackling this problem since around 6am this morning. Now I can take a break for atleast an hour and tackle my other issues.
It is weird though, because I honestly tried to use echo but in the beginning of select name tag. Ofourse that did not work. But I am happy to see atleast I was thinking slightly on the right track. such a small code give me sucha a huge headache. Geesh and thanks a million. If you live in Oregon that would be too cool and if you have spare time. I am looking for a tutor to break down php to me in a way I can understand it.
