Do you get an error here?

4

yes.

I’ve tried every option

5

What does the error say?

6 
ReferenceError: value is not defined
7

Ok, so it’s telling you that you haven’t defined value. Where is value coming from?

8

the value here is chicago

9

No, I meant, where is the variable called value defined? You cannot use variables without defining them somewhere (either in code, using let or const, or by using them in the arguments of the function)
