Yes, the table shown exacts what I need.
do i have to include the date shown in F1 or i can actually just indicate the month, such as jan, feb, etc thought my data given in coloum b is with date-month-year
?
Group | DATE | Amount | Jan | ||
Beta | 1-Jan-13 | $4.00 | Beta | 11 | |
Beta | 1-Feb-13 | $4.00 | Delta | 0 | |
Beta | 2-Jan-13 | $3.00 | |||
Delta | 3-May-13 | $4.00 | |||
Delta | 11-Jun-13 | $5.00 | |||
Beta | 1-Jan-13 | $4.00 | |||
Delta | 1-Feb-13 | $4.00 |
I've try with the formula by :
=SUMPRODUCT(Internal!K5:K10,--(Internal!G5:G15=$A6),--(Internal!N5:N10-DAY(Internal!N5:N10)+1=("1-"&B$5)+0))
Whereby K5 : K10 is the colomn for amount
G5 : G15 is my list if group, beta, delta
A6 = Delta
N5 : N10 is my date : 1-Jan-2013 (for example)
and
B5 = Jan
But shown me #value as my answer
It's working finally. Thank you so much
