Learn Functional Programming by Building a Spreadsheet - Step 11

Tell us what’s happening:

Hello :wave:. It’s MaariCode.

Can someone please help me with this? I don’t understand what is meant by using the .charCodeAt() method directly on the range call.

I look forward to a prompt response. Thanks!

Your code so far

Welcome to the forum @MarriCode

You should use the .charCodeAt() methods directly in your range call.

This means you need the return statement, or the curly braces.

Happy coding
