I'm getting Resource id #5 as the result when I echo $netprofit .. Here's my code. Just learning php so I'm not the savviest yet.
<?php
$netprofit = mysql_query ("SELECT c.*
FROM jem_invoice_payments a
LEFT JOIN jem_invoice_products b ON a.invoice_id=b.invoice_id
LEFT JOIN jem_products c ON b.product_id=c.product_id
WHERE
a.payment_date >= $altstartdate AND a.payment_date <= $altenddate");
?>
