[FTC]: Problem with RobotC servo code

[completelycrazy]

I'm currently trying to program my team's robot's arm. The arm has two servos. I want each servo to move up or down and then stay in the position it moves to using the d-pad or using the A and B buttons. This is the code I'm using - the part of the code that controls servoWrist works, but the part that controls servoElbow does not. I'm fairly certain it's not a problem with hardware - I've tested three different servos using each section of code and all three work with the servoWrist code, but not with the servoElbow code. I also tried using port three instead of port two for the servoElbow code, but that did not help either, so I believe it's not an issue with the servo controller. I'm currently really confused by this because as far as I can tell, the two sections of code are identical.

#pragma config(Hubs,  S1, HTMotor,  HTServo,  none,     none)
#pragma config(Sensor, S1,     ,               sensorI2CMuxController)
#pragma config(Motor,  mtr_S1_C1_1,     motorD,        tmotorTetrix, openLoop)
#pragma config(Motor,  mtr_S1_C1_2,     motorE,        tmotorTetrix, openLoop)
#pragma config(Servo,  srvo_S1_C2_1,    servoWrist,           tServoStandard)
#pragma config(Servo,  srvo_S1_C2_2,    servoElbow,           tServoStandard)
#pragma config(Servo,  srvo_S1_C2_3,    servo3,               tServoNone)
#pragma config(Servo,  srvo_S1_C2_4,    servo4,               tServoNone)
#pragma config(Servo,  srvo_S1_C2_5,    servo5,               tServoNone)
#pragma config(Servo,  srvo_S1_C2_6,    servo6,               tServoNone)
