I am on week 10, I wrote range, But its giving errors, Dont know, what to do? Please Explain

It’s because you’re using a reserved name range as a variable name in the arguments.
Please try changing it, qnd let me know if you face any issues.

Thanks Ishvinder, Solved just now?

Did it overwrite range as a variable?

Yes, range is a reserved identifier, hence was creating an issue in this case.
