if($review): .... but what if no review?

[VFSbrivers]

I am working on one of the pages and there is code to display the review summary if there is a review. What I want to do is show something if there is NO review. Maybe the grayed out stars?

Can someone help me with this?

<?php if($review): ?>
<?php echo $this->getReviewSummaryHtml($_product) ?>

<?php endif; ?>

Thanks!

      /* Do something */

<?php if($review): ?>
    <?php echo $this->getReviewSummaryHtml($_product) ?>
<?php else: ?>
    // display grayed out stars
<?php endif; ?>

Putting the else statement always gave me an error on the page, not sure why. It seems as though it's a simple add-in, but nothing seems to work for me.
