Flipping the X - axis

[cddp14]

Ok. this a simple problem that I know I am just overlooking a small detail. For this years robot we what to be able to push a button to be able to make the back of the robot to become the front and vice versa during TeleOp mode. The only problem is that the x-axis of doesn't adjust when the switch is made. when the robot is reversed and you move the joystick to the left the robot turns to the right and vice versa. Here is my code below:
MyBase->ArcadeDrive(Driver);
if(Driver->GetRawButton(6))// reverse direction of robot
{

MyBase->SetInvertedMotor(RobotDrive::kRearLeftMotor, true);
MyBase->SetInvertedMotor(RobotDrive::kFrontLeftMotor,true );
MyBase->SetInvertedMotor(RobotDrive::kRearRightMotor, true);
MyBase->SetInvertedMotor(RobotDrive::kFrontRightMotor,tru e);

}
if(Driver->GetRawButton(7))// normal configuration
{

MyBase->SetInvertedMotor(RobotDrive::kRearRightMotor, false);
MyBase->SetInvertedMotor(RobotDrive::kFrontRightMotor,fal se);
MyBase->SetInvertedMotor(RobotDrive::kRearLeftMotor, false);
MyBase->SetInvertedMotor(RobotDrive::kFrontLeftMotor,fals e);


}
How can I get the X- axis to switch with the reversal? Thanks in advance. Also, I am using WindRiver.
