When in training, you need to have some button that allows us to give feedback. Sometimes the parser is not seeing the code correctly. There have been a few times where the site never thinks the code is correct when what I typed and the get solution are identical.

allow feedback.

Hello @allanmiller141825787, welcome to the forums!
I moved this thread into community >> suggestions; Feature and Course Requests, as it seems like a suggestion. When you mean a feedback button, do you mean one that generates feedback like the error messages that pop up if your output is not what CC wanted?
