DHT11 temperature and humidity sensor

Hi
I am very new to arduino and am trying to get the temperature and humidity sensor to work. I keep getting error messages such as error compiling for board and expected unqualified id. Please dont criticise me too much for the code because i am very new to this

Temperature_sensor.ino (514 Bytes)

Can I criticise you for posting in the wrong section?

And not posting the error messages?

And attaching the code, instead of posting it?
