There are two recordsets on this page. Your extension will insert the name of the first listed recordset, regardless of the fact that you select the second one when setting it up. As the wrong recordset is noted, the repeat does not work.
Moving the slideshow recordset ahead of the other recordset fixes the problem so that the extension does not overwrite the correct recordset repeat instruction.
While looking into this I found this code: <div class="dmxAbout">Generated by <a href="www.dmxzone.com/go?17708">HTML5 Slideshow Dreamweaver Extension</a> 1.2.3</div> </div>
Not nice to include a hidden link to your website in code that has been bought and paid for. This is not shareware. Embedding a link to your website is rather unethical.
