The test is looking for the type, as well. That’s not included in that query - is the types table linked to one of the other ones with a foreign key?
hmm, I cloned your db with the link you gave and ran that query - I see the column there…
Strange - that’s the problem, but I’m not sure what the cause is. Double check the keys maybe?
Edit: Actually, it looks like you didn’t include that column in your query - try it again with the query I provided.
Double-Edit: The test isn’t passing for me either, let me keep looking…
Triple-Edit: Okay, I found the problem - the atomic mass column has numbers in it, the test is looking for a string. For now, you will have to change those to strings I think. I will file a bug to change it so it will accept either.
