I have one spreadsheet that has the following columns, year end date (2012, 2013, 2011, etc..), account type, account name, assets. One the second spreadsheet I created 2 drop down boxes one has in it the following list: last year, last 5 years, last 10 years, the other has a list of all the account types. I am trying to create a sumproduct formula that will calculate the assets based off of what I select in the drop down boxes. What I am having trouble with is how to create the formula where it will calculate the last 5 or 10 years etc. based off the most current year end date.
An interesting one - I THINK that I'd do this by having a lookup list which contained the year value for each of the drop down choices so you could then use sumproduct (which I assume you are using as multiple condition sumif?) to sum values if the date is greater than or equal to the lookup value - hopefully this makes sense, but if you need further help or clarification do let me know. If it helps, my direct email is firstname.lastname@example.org
