Meghan, welcome to Chief Delphi. Are you part of the FRC program and using the Vex Robotics System to learn how to program? Or are you part of an FVC team as well? Try the white paper,
Vex for the Technically Challenged to start. Chief Delphi has a whole forum just for the FVC program - Click on Chief Delphi at the top of the page, scroll down to Other, then to Vex and FVC is a sub-forum. Vex programming has been discussed there. In addition, don't forget you have a lot of official resources available to you which are linked from the FIRST website - FVC section (the URL right now is
http://www.usfirst.org/vex/resources/). They might help as well, even if you are not on an FVC team...
