Prop proto board USB & servos

I'm working on my first proto board and I'm trying to use the servo circuit. I've soldered in the 4 headers for the servos and the header for the power selection and added a jumper to select 5 volts but I'm not getting power to the servos, I measured the voltage between the ground pin on the servo header and the middle pin and I'm not getting power. Any ideas on what went wrong or what I'm missing?

    The on-off switch has 3 positions: off, on-Propeller, on-Propeller+Servo. It has to be in the last position for the servo power to be turned on (see the Protoboard schematic). Other than that, check your soldering. Check your jumper. The circuit does work.
