Deb, in my previous post I asked the question of whether you were attempting to shoot wirelessly with a K100D using the popup flash as the control.
If this is the case, you'll find that the K100D is not capable of this wireless function as is. You would need another P-TTL flash unit (like another 360) to act as the controller, or get a hotshoe adaptor to have your flash off-camera (but not wireless) or you would need to upgrade your body to a K10D, K200D or any other newer camera.
