Is it simply because you’re getting ahead of the course requirements? I think this step only requires you to move the comments inside the if statement, without actually writing the code yet to do the inserting etc.
I’d remove everything but the comments and see if the step passes then.
(Save the code though, as you can paste it back in in the next step).
doesn’t seem to work
Yes, that is the correct code for that step. You’ll see that the PSQL query commands follow in the next steps.
If it’s not working for you though, you could try a soft reset (from the Project Options menu on top-left)? Then try re-entering exactly the same code again…
Alternatively, I had a little issue with a couple of the steps in this project when my code wasn’t accepted but un-indenting allowed it to pass. (I then re-indented and continued without issue).
