# Sum value between dates problem driving me mad!2

#### Mathew P Bennett

Good Evening All,
Many aplogies for the crappy formatting of my previous post, I have done it
properly (I hope) now.
I am really struggling here, have tried, nested IF's including AND's but am
a bit stumped.
I am fairly familiar with Arrays, but cannot seem to combine all.
I have a data table (as detailed below). I simply wish to calculate the
expected totals per month.
Any help & assistance with this would be most welcome.
Cheers,
Mathew

Mathew,

Your looking for a sum between dates so i'm assuming that
you want your sum to add up column C (Day Rate) when
the ?Start Date? falls between April 1 and April 30. Or
did you want the sum based on the Finish Date?

Perhaps you could provide a sample output, just so that
we can verify our solutions work to your specifications.

Mathew,

=SUM(IF((IF(\$B2:\$B40 said:
0,(IF(\$B2:\$B40<=(D\$1+29), IF(\$B2:\$B40<>"",\$B2:\$B40,D\$1+29), D\$1+29))-IF(\$A2:\$A40>=D1,\$A2:\$A40,D1) + 1,0)*\$C2:\$C40)

Watch out for line wrapping, it's one gigantic formula.
Note: built this formula for april (note the 29's - one day
less than in the month) change accordingly for different
months.

Thought i'd explain somewhat,
I assumed that a blank finish date means the project is
ongoing. If a project spans two months it's broken up
(based on the # of days worked in each month)

Don't know how I forgot, but . . .

That formula has to be array entered (control + shift + enter)
