echo '<td valign="top">';
echo '<td>' . '<input type=submit class="form-submit" name=add value=' . ' </td>';
echo '</td></tr>';

echo '</form>';
echo '</table>';
mysql_close($con);

Thanks in advance !!

This is not the way to do it. If you change the cars in the select,it means you have to change your DB table. That's just not practical.

You should be looking to create a table like this:

Product, Item, Description, Extra, Valuta, Price, Nummer, Car_make_id

With another related table for car_make:

Car_makes

car_make_id
car_make_name

You then just need to query this table to build your html select, e.g.

SELECT * FROM car_makes

while(...){
    $options.= "<option value='{$r['car_make_id']}'">{$r['car_make_name']}</option>";
}
