I am not sure why this is happening. Programming in javascript. error output below.

Sorry for the late reply, if I remembered correctly, there are certain lessons preventing users to write prompt() in the test learning environment (don’t ask me why). That is probably what causing the error. Else, you can head on to a cloud IDE such as https://repl.it/languages/javascript, paste your code to see whether your prompt() is working well.
