Unable to invert motor

[christheman200]

Hi all!
I have the following code in my main robot class, and it is giving me a number of exceptions which I can't conquer:

MainDrive.setInvertedMotor(Talon.kRearLeft, true); 
	MainDrive.setInvertedMotor(Talon.kRearRight, true);

Exceptions:
First line:
- Syntax error on tokens, delete these tokens
- Syntax error on token "(", < expected
Second line:
- Syntax error on tokens, TypeArgument1 expected instead
- Syntax error on token "(", , expected

Any and all help is appreciated!
Thanks, Chris
