I see the link I need to make the panda but then it disappears and turns into https://worker.mturk.com/projects?ref=w_fr_srchAmazon redirects the url, so you lose the group ID.
If you're using HIT Finder or HIT Scraper to grab hits (or however you're grabbing them), you'll need to right click to grab the link and paste it somewhere (not the search bar). You can use something like this.
Enter into your search bar, hit enter:
Code:data:text/html, <html contenteditable>
Paste the url there, and pull the group ID, then you can add that into PC.
