problems with SELECT and related tables

[David Youngblood]

I am running Apache/PHP 4/MySQL 3.23 on a Win98.

The following statement will not execute in PHP MyAdmin or through the
browser. However it does run under my SQL tool SQLion:

SELECT contacts.contactId,contacts.firstName,orders.orderId
FROM contacts INNER JOIN orders
ON contacts.contactId = orders.contactId;

I really need to get this figured out for my local development to work –
any ideas?
