I am attempting to pull data from 2 tables.  My SELECT statement seems ok.  But the next line: while ... etc. is giving me an error of "Supplied argument is not a valid MySQL result resource.".  But this is the way I usually show my data and it works fine when only 1 table is involved.  Is there a different way of showing your data when pulling data from more than one table?

$result = @mysql_query('SELECT orders.orderid, orders.amount, orders.date
	from customers, orders WHERE customers.name = "Don Hansen" and
	customers.customerid = orders.customerid');

while ( $row = mysql_fetch_array($result) )
{
	$zorderid = $row['orders.orderid'];
	$zamt = $row['orders.amount'];
	echo (str_pad($zorderid,4,' ') .  str_pad($zamt,6, '  ') . '<br>');
}

Thanks,

Doug -

the data would actually be accessed as the actual fieldnames without the 
"tablename."

while($row=mysql_fetch_assoc($result))
{
   foreach($row as $key => $value) {
      echo '$row['.$key.'] => '.$value.'<br />';
   }
   echo '<br />';
}

the above snippet will allow you to see the values being passed to $row 
by mysql_fetch_assoc();

hope this helps,
