Hiya Jacob,
From your description of what you've done (and the files all seem to be in place) you should be seeing the gallery working properly in your product detail page. But when I click to view the source code of that page, the code for your ProductLongDesc div looks like this (I have removed the description text you entered):
<div id="ProductLongDesc"><input id="2" type="hidden" theme="dark" name="powergallery" value="/homepages/25/d319221346/htdocs/powergallery/galleries/ribbon_lightbox_powerstore/index.php"></div><p></p></div>
</div>
It seems to have failed to pull the required info to display the ribbon gallery in to the html of the page. You should be seeing something like the following for the contents of the ProductLongDesc div:
<div id="ProductLongDesc">
<style type="text/css" media="all">
@import url("/PowerGallery/css/slimbox/slimbox.css");
@import url("/PowerGallery/galleries/ribbon_lightbox_powerstore/css/common.css");
@import url("/PowerGallery/galleries/ribbon_lightbox_powerstore/css/dark.css");
</style>
<script type="text/javascript" src="/PowerGallery/js/mootools-core.js"></script>
<script type="text/javascript" src="/PowerGallery/js/mootools-more.js"></script>
<script type="text/javascript" src="/PowerGallery/js/slimbox.js"></script>
<script type="text/javascript" src="/PowerGallery/galleries/ribbon_lightbox_powerstore/js/gallery.js"></script>
<div class="pg-rlp">
<!-- ribbon -->
<div class="ribbon">
<div class="prev"></div>
<div class="thumbs-wrapper">
<div class="thumbs">
<div class="thumbs-ribbon-scroller" >

</div>
</div>
<div class="next"></div>
</div>
</div>
</div>
</div>
The only way I can replicate the results that you are getting is if I change the code (<div id="ProductLongDesc"><?php require_once('wa_evaluate.php'); ?>
<?php echo wa_evaluate($row_WADAProducts["ProductLongDesc"]); ?></div>) in the 'Products_Detail.php' file in the PowerStore 'Admin' folder instead of the Products_Detail.php in the the PowerStore root directory (there are two 'Product_Detail.php' files).
Not sure if this might help diagnose anything.
