Thanks for the reply...
When you say "the code seems incomplete" you are right on the money. I know
just enough about sql and php to get me into trouble...in other words I can
usually get done what I need to but it's not always the best (or proper) way
to do it...and other times it just doesn't work at all.
I added the line... error_reporting( E_ALL ); ...that's a life saver,
thanks for that one...
....however, when I added the... echo htmlspecialchars(
$_SERVER['PHP_SELF'] ); ...I receive the error...
Parse error: parse error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting
T_STRING or T_VARIABLE or T_NUM_STRING in
/usr/www/users/myaccount/myfolder/admin/print_supplier_order.php on line 67
....if I leave the line the way I had it before, I get the error...
Notice: Undefined variable: enter_data in
/usr/www/users/myaccount/myfolder/admin/print_supplier_order.php on line 73
....this is variable $enter_data which is the name I gave the Submit Button
(name=\"enter_data\").
Basically all I'm trying to do is execute a SQL statement by pressing a
Submit Button on a form...but obviously I don't know how...
Here is the code I have that does list the products to be ordered, but has
the error mentioned above and of course will not work if I press the submit
button...

if($totalrows==0){echo"<br><br><p align=\"center\">No products in your
inventory</p>";}
if($totalrows!==0){
while ($row = mysql_fetch_array($sql_select)){
$product=$row["product"];
$title=$row["title"];
$quantity=$row["quantity"];
$price=$row["price"];
$cart_order_id=$row["cart_order_id"];
//echo"

<td align=\"center\">$currency $price</td>
<td align=\"center\">$cart_order_id</td>
</tr>";
}// end while
echo"</table></td></tr></table><br>";
}
echo"</body></html>";
?>
I would assume the problem lies somewhere in the line...
$sql = mysql_query("UPDATE cubecartstore_order_inv SET order_from_supplier
= '0'");
....I don't know how to use the $sql variable...I tried taking "$sql =" out
of the line but that didn't work either...
I just want mysql_query() to execute the SQL statement when I press the
submit button...
Thanks for any help you can provide,
