Control flow - exercise 3: FizzBuzz

here is a screenshot of the code I wrote

I tried to make the FizzBuzz exercise, but every number I fill in it says ‘Not a Number’
does anyone know how I can fix this?

many thanks,

You put semi colon after each if so it is an empty statement. The next line is return "Not A Number" which will happen every time. Hence the code under being vanished because it detected dead code. It will never get there.

Another hint is that the return statements are not indented from if statements while they should.

You seem to be using VS Code.

Use +Alt+F to format your document.
Remove a semi-colon after an if statement and try again.
Repeat.
