How do you fix this specific compiler error?

Whenever I click the play button of my 3D Game on my Mac, it displays a message that says I must fix all the compiler errors before running the game. When I click the console, it says "Assets/OutPost/Resources/Scripts/CameraMode.js(5,25): BCE0018: The name 'MouseLook' does not denote a valid type ('not found'). Did you mean 'UnityStandardAssets.Characters.FirstPerson.MouseLook'?"

So, I double clicked it and went to the line of code that it said was messed up. Then, I deleted all the "mouselook" words and replaced them with "UnityStandardAssets.Characters.FirstPerson.MouseLook". The code in MonoDevelop said there were no errors, but Unity still said there was a compiler error. Thanks!
