I have an Excel document that has a date column (A) and a column containing strings (B) one one sheet. On another sheet, I am doing calculations. If the cell in column A is between DATE(2012,1,1) and DATE(2012,6,1) AND the same row in column B contains "string" in any part (string) then it should count that row. Google mentioned using SUMPRODUCT but I was only able to get date between to work. Below is the SUMPRODUCT for date between.
=SUMPRODUCT(--('Sheet1'!A:A>=DATE(2012,1,1)),--('Sheet1'!A:A>=DATE(2012,6,1)))
I tried using this for the final value but it is incorrect.
=SUMPRODUCT(--('Sheet1'!A:A>=DATE(2012,1,1)),--('Sheet1'!A:A>=DATE(2012,6,1)),--('Sheet1'!B:B="*"&"string"&"*"))
EDIT: Apparently the above works, but the string must be EQUAL to the value. * is not being recognized as a wildcard.
Thanks.
