It worked perfectly. How about if I need to add not the entire column,
but
the one corresponding to today's date and the previous cell only, again on
a
rolling basis? In other words, on the 21st it returns 11, on 22nd 9, on
the
23rd 8 and so on. Can that be done?

Thanks.

Hi,

take your criteria out of the column then sum the entire column based on
the
criteria

=SUMIF(A:A,"<="&C1,B:B)

Sums all coulm B for a date in column A <= C1

I am trying to create a formula that looks for todays date in a table
and
returns the sum of daily entries for the month prior to the date. In
the
sample below =vlookup(E1,A1:C2,2) instead of returning 6 value from row
#2,
it will return 11, the sum of all values prior to the one assigned to
the
date. Furthermore, can I set it to change the range tomorrow, adding
yet
another cell to the sum for a return of 14?

A 11/20 5

B 11/21 6

C 11/22 3

D 11/23 5

E 11/20

Thanks
