In E21, add

=IF(D21=0,0,SUM(INDEX($D$21:D21,MAX(1,MAX(IF($D$21 :D21=0,ROW($D$21:D21)))-MI
N(ROW($D$21:D21))+1)):D21))

which is an array formula, it should be committed with Ctrl-Shift-Enter, not
just Enter.
Excel will automatically enclose the formula in braces (curly brackets), do
not try to do this manually.
When editing the formula, it must again be array-entered.

Copy this formula down.

I thought that a section of the form may help.

Thanks Bob.
But I am sorry I omitted a crucial part, after the employee takes a day
off
the clock restart and the employee can work another 70 hours. The day
off
can happen at any time during the month.

I am new at creating formula in Excel. I am trying to create a
specific
timesheet. The employee can work a maximum of 70 hours in 7 days.
I have
created this formula, which works for the pass 6 days but when I use
it
for 7
days, I have too many argument. I also have to create a formula for
13
days
and 14 days (maximum of 120 hours).

Works for pass 6 days:


=IF(D25=0,"0",SUM(IF(D20=0,(D21:D25),IF(D21=0,(D22 :D25),IF(D22=0,(D23:D25),I
F(D23=0,(D24:D25),IF(D24=0,D25,IF(D20:D250,(D20:D 25),""))))))))

Too many argument (7 days):


=IF(D26=0,"0",SUM(IF(D20=0,(D21:D26),IF(D21=0,(D22 :D26),IF(D22=0,(D23:F26),I

F(D23=0,(D24:D26),IF(D24=0,(D25:D26),IF(D25=0,D26, IF(D20:D260,(D20:D26),"")
))))))))
