I think that in your database it is : substring(loc, 1, 3) as loc1 Anyway, the error is not where you are getting the message, the query failed and this you don't have a valid resource to ask the number of rows or do anything else. You should add an 'or die("message: " . mysql_error()) to your query to trap the error.
