$num = mysql_num_rows($test); echo $num;
If it returns 0 you have no entries, if nothing happens then you have problem with your query or connection. If you get a number then there is something else wrong. This is a test I haa to use to sort out some code. It is best if you use mysql_error() whenever possible during testing so that you can know exactly what goes wrong where. But I am a noob. There are probaly others with better answers.
