Don't cry, but no one probably does. I suspect that people who want full manual control for a twin external flash setup, will probably use non P-TTL triggering. Just to check the basics, the Pentax flash is on camera? If you set the Pentax flash to M mode, then it probably won't send out the P-TTL pre-flashes, which is how it communicates wirelessly with the Metz flash. To get the Metz to fire in Servo mode, you might have to not select wireless in the camera. Or go back to P-TTL, although I think the camera will get 2/3 of the exposure from the master flash and 1/3 from the slave when an external flash is mounted on the camera, which is why I asked where your Pentax flash was mounted. If you use the pop up flash as a master controller with 2 external flashes mounted off-camera, you will get a different proportioning of the flash power.
