Your code challenge appears to have a broken Javascript file in it? (or at least in this instance of the virtual machine

The site is unable to process my code attempt at the solution, here's what I intended to submit.

select count(id) as ordered_yesterday_and_shipped from orders where ordered_on = date("now", - 1 day) and status = "shipped";

Looking in the dev console, it looks like a JS error "Uncaught SyntaxError: Unexpected end of input (at VM693 foundation-A187849-72ad-44c6-83bc-3d4f458b85e71.min.js:392:5)"

Attempting to debug the challenge engine code is likely to cause more confusion than help.   :see_no_evil:

The issue here is with the syntax of the solution. The modifier for the date function must be a string, so the value needs to be enclosed in quotes. Also, there should not be any space between a sign and the number it applies to. The space causes it to be interpreted as an operator instead of just a sign.

Thanks, I did eventually get it to accept the answer. Enclosing the modifier in quotes probably helped 😬

I guess what made me think that it was a deeper error was that it wasn't even processing my solution to tell me whether it was incorrect. It would just hang and tell me to reload the page and "Don't worry your code is safe" then would delete my code after reloading, and continue to not work.

When I ran it, I got "Bummer: There's something wrong with your SQL statement. Please review your code and try again."

That "reload" issue is one I've seen from time to time, and it generally seems to be a temporary server issue that goes away after a while.
