Noob Raspberry pi python errors

Trouble Kelp · October 10, 2014

I've been having trouble with a python project I've been working on. I got my pi to turn on and off the GPIO pins from a webpage following a guide but now I'm trying to get it to work with PWM controls. I'm pretty new to programming and I don't know a how all of this program works so I tried to change it as little as i could to change PWM % instead of turning it on and off. When i try to run the code this error comes up

AttributeError: 'module' object has no attribute 'setmode'

I've tried updating everything and I have the newest software.

This is my code
