Sum variable range of cells using "today's" date as starting point.
- by Jason
How do you sum a variable range of cells based upon today's date in MS Excel 2003.
Spreadsheet format:
Variable range = # of days to sum
Date range = listed in row 1, 1 day per cell (example A1=1/1/10, B1=1/2/10, C1=1/3/10....)
Numbers to be summed - listed in row 2, X number per cell (example A2=8, B2=6, C2=1.....)
example problem:
IF variable range = 2 & Current Date = 1/2/10 then...Sum(b2:c2)=7
I am able to sum the entire row based upon current date using the following formula but am not able to add the variable range to the sum function.
=SUMIF(A1:C1,"="&TODAY(),A2:C2)
