Magento: How do I separate the display of multiple attributes?

[OsPrOd]

I am using this code to display (on the frontend) all assigned attributes of a product in Magento: \[code\]<?php if ($_product->getData('metal')): ?> <?php echo nl2br($_product->getResource()->getAttribute('metal')->getFrontend()->getValue($_product )) ?> <?php endif; ?>\[/code\]I need to separate each item with a bullet point \[code\]•\[/code\] and a break \[code\]<br/>\[/code\]. How would I edit this code to reflect those changes?Thanks in advance._Sam
