Try this **array** formula:

=SUM(INT((EndDate-WEEKDAY(EndDate+1-{2,3,4,5,6})-StartDate+8)/7)*
IF(Location="office",{7.5,7.5,7.5,7.5,7},{8.25,8.2 5,8.25,8.25,4}))-
SUMPRODUCT((Holidays=StartDate)*(Holidays<=EndDat e)*
(WEEKDAY(Holidays)={2,3,4,5,6})*IF(Location="offic e",
{7.5,7.5,7.5,7.5,7},{8.25,8.25,8.25,8.25,4}))

To enter an **array** formula, after typing or pasting it into the cell, hold
down <ctrl<shift while hitting <enter. Excel will place braces {...} around
the formula.

I used named variables to make the logic a bit more clear and account for the
possibility that the work was taking place "office-based" or not.
