Pagination using next button returns no results

Hi folks. I've created a scraper for ebay using this video as a guide: Web Scraper << How to >> Set up pagination with "Next" button using Element Click selector

I can see the scraper paging through but it doesn't return any results when I press "refresh".

Any ideas for how to return results using the next button for paging?

Here's my sitemap: {"_id":"aaa-perry","startUrl":["blackberry classic | eBay":0}]}
