When shooting outdoors make sure the IR sensor (little round red glass eye on the side of your speedlight) is facing the camera, you may need to face the body of the flash in the opposite direction and turn the flash head 180 degrees to get the eye facing the right way. When inside this isn't normally a problem because the flash from the camera bounces off the walls and hits the IR sensor. Also bright sunlight can cause issues for the IR system, but at around 6' it should be fine. The IR has a range of about 30' in ideal conditions but try to keep the flashes as close to the camera as possible.
