Hello @rimab647,
Welcome to the FCC community 
Strange. Your code seems to be OK. Try the following:
- clear your cache (browser history) and try the same code again
- check to see if you get the same result in another browser
Are you still getting the same error code?
I see you’re using Edge. Try updating to the Chromium version or using the Chrome browser.
As an aside,
If you have a question about a specific challenge as it relates to your written code for that challenge, just click the Ask for Help button located on the challenge. It will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.
Thank you.
