Hello all, I receive the following message in Trailhead. I think that the exploration and filter are set up properly. I don't know what I am doing wrong. Would you please help?

I am unable to complete the hands-on challenge "Create a lens that shows which industry is buying the most laptops" I continue to receive the following error even after multiple attempts.

"Challenge Not yet complete... here's what's wrong: 
The 'Top Laptop Industry' lens does not appear to have the correct query. Please check the requirements and ensure everything is setup correctly."
