on the admin/orders_details page, there should be the following code to show the address and phone number:
<p class="nobottom">
<label class="readonly-bottom">Address:</label>
<?php echo($row_WADAorders['OrderShipName']); ?>
</p>
<p class="nobottom">
<label class="readonly-bottom"> </label>
<?php echo($row_WADAorders['OrderShipAddress']); ?> <?php echo($row_WADAorders['OrderShipAddress2']); ?>
</p>
<p class="nobottom">
<label class="readonly-bottom"> </label>
<?php echo($row_WADAorders['OrderCity']); ?>, <?php echo($row_WADAorders['OrderState']); ?> <?php echo($row_WADAorders['OrderZip']); ?> (<?php echo($row_WADAorders['OrderCountry']); ?>)
</p>
<p class="nobottom">
<label class="readonly-bottom"> </label>
<?php echo($row_WADAorders['OrderPhone']); ?>
</p>
is the customers phone number being stored in the OrderPhone column of the orders table?
