Whenever Census_Tract_2000 is changed, Census Tr Certainty 2000 must be changed accordingly:

If Census_Tract_2000 is 999996 or 999997 (waiting for geocoding), then Census Tr Certainty 2000 must be set to blank.
If Census_Tract_2000 cannot be tracted (999993-999995 or 999998-999999) then Census Tr Certainty 2000 must be 9.
If Census_Tract_2000 is tracted and a Census Tr Certainty 2000 code is available (whether through geocoding, linking a tumor with a tracted address, or manual entry of a Census Tr Certainty 2000 value) the available Census Tr Certainty 2000 code should be used.
If Census Tract 2000 is tracted, but Census Tr Certainty 2000 is not available, Census Tract 2000 should be set to 999996 and Census Tr Certainty 2000 should be set to blank
