almost there ... This formula is giving me the answer I'm looking for, but I'm still looking for a little more.
D4 =IF(ISBLANK($C$4),$AA$4,IF($D$2>=$C$4,$C$4-$B$4,IF($D$2<$C$4,$D$2-$B$4,"")))
E4 =IF(ISBLANK($C$4),$AB$4,IF($E$2>=$C$4,$C$4-$B$4,IF($E$2<$C$4,$E$2-$B$4,"")))
F4 =IF(ISBLANK($C$4),$AC$4,IF($F$2>=$C$4,$C$4-$B$4,IF($F$2<$C$4,$F$2-$B$4,"")))
G4 =IF(ISBLANK($C$4),$AD$4,IF($G$2>=$C$4,$C$4-$B$4,IF($G$2<$C$4,$G$2-$B$4,"")))
D2= 7/4/08, E2= 7/11/08, F2= 7/18/08, G2= 7/25/08, If B4= 7/2/08 and C4= 7/8/08, then I want D4= 2, E4= 6, F4= --, G4= --
Can this be done?
