Hi, here’s my problem: I’m absolutely sure my code does what it needs to, still I can’t pass the last test and the tests that depend on specific content of cid array only pass when I edit this array to match the test conditions. I suppose the lesson is broken? Or is there a workaround?

Without seeing your code it’s impossible to say. From the description it sounds like your code might depend on some additional global variables, instead of performing certain calculations every time purchase is made.

Hey there,
Please update the message to include your code. The code was too long to be automatically inserted by the help button.
When you enter a code, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
See this post to find the backtick on your keyboard.Note: Backticks (`) are not single quotes (').

Try putting that global order array inside purchase.
Really, I’d get rid of this global variable.
