Xbox 360 Controller Triggers

[MathMaven]

We (team 3175) have been testing the use of an Xbox 360 controller to control our arm and have found issues with the trigger buttons. When using the trigger buttons to control a window motor, we find that our program is reading axis z-axis values that do not correspond to how we are pressing the trigger buttons.

In one case, we let go of the trigger buttons and the value sent to the TeleOp.vi was 1. However, when looking at the controller through the control panel while running the program, it shows that the z-axis is in a neutral position.

Why is this happening? Is this a fault of the controller's hardware, the programming (which I have attached to this thread), or something else? We'd really appreciate some answers.
