Data scraping multiple pages: there is no next page selector

Hi all, I am a newbie.
So I wanted to make a robot that will download data from this site “”. As you can see there is no next page selector here, so I decided to make a variable (""). When I have done this, the page goes back to the main page instead of the next one. Does anyone have any advice?

I didn’t add it in the post, but changed it to something like this: webctrl aaname=’*’ parentid=‘wrap’ tag=‘A’ .
