I copied and pasted the code from the webserver.py into my pico w and got this error. ``` Traceback (most recent call last): File "<stdin>", line 72, in <module> NameError: name 'stateis' isn't defined ``` if I comment out this line and line 76 I get a different error ``` Traceback (most recent call last): File "<stdin>", line 43, in <module> OSError: [Errno 98] EADDRINUSE ``` Is there any way to fix this?
