Thanks for the quick reply. The order by stuff is gone now, it was an
'artifact'. hehe. Anyway, I added the where clause so my query looks like
this:
$sql = "update refurbs set qty = qty - $buy where part_number =
$part_number";
But when I try to run this I get an error -
Parse error: parse error, unexpected $ in
/usr/local/www/data-dist/auth_dealers/refurbs-test.php on line 102
I don't see an rogue $'s in the code.
(Eventually the form will submit to another page which will email the info
to a person here in our office).

Now the code looks like this -
===============================================================
<form action="<? PHP_SELF ?>" method="post" name="refurbs">
<table summary="" border="1" cellpadding="5" cellspacing="0"
width="90%" align="center">
<tr>
<td class="small" bgcolor="#ffffff">Part Number</td>
<td class="small" bgcolor="#ffffff">Description</td>
<td class="small" bgcolor="#ffffff">Quantity</td>
<td class="small" bgcolor="#ffffff">List Price</td>
<td class="small" bgcolor="#ffffff">Special Price</td>
<td class="small" bgcolor="#ffffff">Put on Hold
</td>
</tr>
<?
if (isset($submit)):
$sql = "update refurbs set qty = qty - $buy where part_number =
$part_number";
$result = mysql_query($sql);
$Colors = array('#ffcc99','#ffcc33');
$I = 0;
while ( $row = mysql_fetch_array($result))
{
printf("<tr bgcolor=" . $Colors[ $I ++ % count( $Colors ) ] .
"><td>%s\n</td>\n", $row["part_number"]);
printf("<td>%s\n</td>\n", $row["description"]);
printf("<td>%s\n</td>\n", $row["qty"]);
printf("<td>%s\n</td>\n", $row["list"]);
printf("<td>%s\n</td>\n", $row["special"]);
printf("<td><input type=\"text\" name=\"buy\" size=\"2\" maxlength=\"2\">
</td></tr>\n");
}
?>
</table>
<table summary="" border="0" cellpadding="5" cellspacing="0"
width="90%" align="center">
<tr>
<td><br /><div align="center"><input type="submit" name="submit"
value="Submit" /></div></td>
</tr>
</table>
</form>
