Errors when uploading servo sweep example

I'm very green to the Arduino world and hoping someone can help me resolve these errors. I'm running the servo sweep example in Arduino 1.6.6 and get the following errors. Thank you in advance!

avrdude: stk500_rcv() : programmer is not responding

avrdude: stk500_getsync() attempt 10 of 10:not in sync:

Problem uploading to board.

It looks like the port that you have selected is not the port that the Arduino is connected to.
