Quadruped_Robot

I have a class called Quadruped_Robot that has four structures, fRight, fLeft, bRight, and bLeft that inherit from a base structure, Leg. In Arduino, I am trying to actuate 8 servo motors by cycling through each one, and the four structures hold the servo driver channel value. I've created an array of pointers to the four structures, so that the function, actuateLeg, can send PWM signals to the appropriate channel determined during runtime. However, none of the servos respond, and upon inspecting the values given by myLeg->channels[0] and myLeg->channels[1], they report values that are in the range of thousands, both positive and negative. However, the values should be between 0 and 7. Why are the channel values incorrect when I try to access them using the -> operator?
