Drive System--Variable to Speed Controller

[Team3266Spencer]

You can't put leftSpeedController(double) on that line near the end. You need to call a method from that object that sets its speed to the double. I havn't worked with robot builder or whatever you're using but NetBeans should give you a list of options if you type "leftSpeedController." I'm guessing it will be "leftSpeedController.set(double);" set(double speed) being the method you actually want. What you're telling it to do right now is to call the method leftSpeedController(double d) which is non-existent.
