Keep getting a Checksum error with DHT11

Hi All,

I am trying to use a humidity and temperature sensor from Sparkfun with the DHT library and sample code but I keep getting a Checksum error (case: DHTLIB_ERROR_CHECKSUM). I'm not exactly sure what this means and I would really appreciate it if someone could explain to me what might be causing this problem and how I might be able to fix it. Thanks in advance!

Problem solved. My circuit was a bit off. If anybody has the same problem, try the circuit and code in this link to get started:
