No connection between Robot and Controller!

#1

When I turn on my robot and my controller, the controllers LED’s are off, except VexNet, which is on, and blinks twice every half second, on the robot, VexNet and Game are blinking yellow rapidly, and Robot, which blinks once every half second. Our Controller and robot were connecting just fine earlier today,. The only thing that has happened since Is I have added coding for a partner joystick. ever since then, the robot is not connecting to the controller.

Code

task main ()
{
int joy_x;            
  int joy_y;            
  int threshold = 10; 
  while(1 == 1)
  {
 		joy_x = vexRT[Ch4];  .
    joy_y = vexRT[Ch3];   

    
    if((abs(joy_x) > threshold) && (abs(joy_y) > threshold) && (joy_y > 0))
    {
      motor[backLeftMotor]  = (joy_y + joy_x)/2;
      motor[backRightMotor] = (joy_y - joy_x)/2;
    }
    else if((abs(joy_x) > threshold) && (abs(joy_y) > threshold) && (joy_y < 0))
    {
      motor[backLeftMotor]  = (joy_y - joy_x)/2;
      motor[backRightMotor] = (joy_y + joy_x)/2;
    }
   
    else if((abs(joy_x) > threshold) && (abs(joy_y) < threshold))
    {
      motor[backLeftMotor]  = joy_x;
      motor[backRightMotor] = (-1 * joy_x);
    }
    // Standing still: (both abs(X) and abs(Y) are below the threshold)
    else
    {
      motor[backLeftMotor]  = 0;
      motor[backRightMotor] = 0;
  	}
    {
    	motor[armLeftMotor] = vexRT[Ch2Xmtr2];
    	motor[armRightMotor] = vexRT[Ch2Xmtr2]; 
    }
    
    {
    	
    	motor[intakeLeftMotor] = vexRT[Ch3Xmtr2]; 
    	motor[intakeRightMotor] = vexRT[Ch3Xmtr2]; 
  	}
  }
}

Please help, as we have a competition on Saturday!

What colors are each of the lights blinking? I will need this information in order to debug the problem using the VEXNet Cortex User Guide (http://content.vexrobotics.com/docs/VEXnet_Cortex_UserGuide_081811.pdf).

Also, please follow all of the steps in the ‘Getting Started with VEX Cortex - Wireless’ guide on the ROBOTC wiki ( tags for me to take a look at. as this covers many of the common setup problems you may encounter.)
