any one of you have experienced this non-track-course?
Verification does not accept any code, instead of it always appears notification "Oops, try again. undefined"!
I was looking for information on this issue in other places in search of a solution, but so far without success...
I want to hear the views of guys who have completed or attempted to complete this course. I still have hope to complete it fully, because I found an interesting comment on the forum from Haley here hello factorial. Error: Undefined.
If someone knows something about this issue, please respond to me!
Thank you in advance for any information,
