Tell us what’s happening:

I have added the if statement and the return statement I am not sure what is going wrong

I don’t see a request to add this log so I would remove this line.

I have removed it  but it is still not working

I don’t see an obvious issue so I will suggest that you click reset in case something was changed by mistake and then retype the if statement.
