I have a SB900 set to remoteand the D7000 Set to commander mode Built in Flash set to --Group A TTL with 0 compbut everytime i try to take a picture, the D7000 flash still fires.. along with the SB900isnt -- meant to keep the on-board flash from firing.

You'll find much more about this over in our Speedlights and Lighting Forum, but briefly... The built-in flash has to emit pulses of light, even when set to "--", as that's how the remote Speedlight is controlled and triggered. The amount of light emitted will not affect the exposure unless you are very close to the subject.
Please respond to this question in This Duplicate Thread in the Speedlight forum.Thank you.
