Hi,
Try using the Go Through All Pages premade at File -> Online Premades and use a kind that selects the ">" button. Make sure this kind works on many pages and that it doesn't work (this is important) on the last page. If it still works (it selects something) on the last page then you'll need to add a javascript gatherer to help Helium Scraper recognize the difference between this next button and every other next button. If you need help creating this gatherer let me know (I'd need to have the URL to the page).
