First of all thank you to anyone that helps!
We (my son and I) are TOTALLY new to robotics and we are trying to make a robot follow a line. I have used google and found quite a bit of information. Of course I am posting because we have encountered a little issue.
We have purchased RedBot Kit (https://www.sparkfun.com/products/12697). We have downloaded the arduino software and tested the robot with the BLINK code and it worked.
We added the Redbot_ Arduino_Library and RedBot-Master.zip - Link from GithUb (both of these are referenced on this page under Documents - https://www.sparkfun.com/products/12697) and the RedBotKit Libraries.
We then opened Arduino software and Select Examples, RedBot, Demo it opens up the following CODE (See below). When I verify/Compile the code i get the following error - error: ‘followNoCal’ was not declared in this scope. Could some one please let me know what i am doing wrong?
Thanks…

This is a simple line following demonstration using the RedBot.
It uses three of the line detection sensors to follow the line, and the
accelerometer to start the line following behavior.
