Unanswered: Formula to sum through a specified year
I'm sure this has been posted before be was not able to find any prior threads. Attached is an example data file. What i'm trying to accomplish is located on sheet2. Sheet 2 contains two columns (Cumulative total & Year). I am trying to use the data located on sheet1 to sum in the cumulative total column based on the year identified in sheet2.
So for example, if the year in sheet2!B2 is 1995, sheet2!A2 should be a cumulative total of all prior years through 1995. If sheet2!B2 is 1994, then the sheet2!A2 total should equal the sum of all prior years through 1994.
I haven't had much luck in trying to crack this one, so any help would be greatly appreciated!
