Hello arun!

If you refer this website:


As well as the problem statement in this challenge. You can see:

The blur-radius and spread-radius values are optional.

That means in the code you provided they didn’t add a spread radius value!

thanks man. And one more doubt, I’m not able to link a YouTube video in my project. It says ’ www.youtube.com refused to connect’ how can I get rid of this.

I would like you to post the problem.

As I cannot guess what the exact problem it might be. Like the more context you can provide and what project, the faster people here will give you the solution!
