The code below sorts properly but cannot distinguish between 10 and 100?

$sql="SELECT * FROM master WHERE mod_id ='bio' ORDER BY order_id";

it sorts: 10, 100, 20, 30, 300, 400

INSTEAD I want in to sort: 10, 20, 30, 100, 300, 400

What do I need to add to the query for it to recognize the difference between 10, 100, 1000 AND SO ON?

FYI the values 10, 100, 20, 30, 300, 400 are being pulled from the field "order_id"

Sorry I am a newbie. This observation was key as it was a VARCHAR - I changed it to SMALLINT and everything works fine - THANK YOU...
