Other folks who are more familiar with the tracking example can undoubtedly provide more information but I'm not sure that simply dragging-and-dropping that icon will work. The Basic (and Advanced) Robot Main VIs already perform a lot of the communication and watchdog configuration. You MAY be "configuring everything twice" by doing what you did. You might need to dig into the example and copy/paste certain elements.
Regarding battery voltage, please check the component datasheets at
http://www.usfirst.org/community/frc....aspx?id=10934. In particular, chapter 3.4 describes the Analog Breakout and how it can be configured to measure battery voltage. All you need to do is attach a jumper on the outer 2 pins to feed battery voltage into Analog Input 8. Rule R64 requires that you install such a jumper.
