=IF(AND(B2=0,C2=0),1,0)

Looking at the example below

Col A Col B Col C Col D Col E Col F
date a date b time diff date c time diff complete
14-Apr-06 14-Apr-06 0 20-Jun-06 67
16-Apr-06 19-May-06 33 04-Jul-06 46
14-Apr-06 15-Apr-06 1 20-Jun-06 66
16-Apr-06 19-May-06 33 -38856

For each row, I need to enter a "1" in Column F only if the values in
Columns C and E both has positive values equal to or greater than 0.

Can you help please
