The return value of mysql_query() is *NOT* a value of what you
selected. It's a result set. Fetch a row (you might have gotten
more than one row) from the result set (e.g. with $r =
mysql_fetch_array($OrderID).) Then look for the column (e.g.
$r['OrderID'] you asked for, and THAT'S the value you want to put
in the query.
Also, when you're debugging something, don't put @ in front of
function calls. Also, print out the SQL being passed to mysql_query.
You never set $id (unless it's hidden in your includes).
