GWS Park HPX F Servo

Hi,
I am brand new to Arduino so this is probably an easy one. I am working on a project that requires a couple of servo motors. I had one from the Sparkfun experiment kit that I bought and that one works fine. However, I bought a coupl of GWS Park HPX F servo motors and they just start moving back and forth when I send them the signal to move to a specific location.

Any ideas. The wires are brown (-) red(+) and orange signal.

If you are trying to power the servos from the arduino, that can cause problems. If you are using an external power supply for the servo, the power supply ground needs to be connected to the arduino ground.
