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 aidan.heritage@virgin.net

I have provided first hand support since `95 for Microsoft Office majoring in Word and Excel - support for all versions from 2 onwards. I'm based in the UK, so please allow for time differences when asking me questions from other parts of the world!


My background is in the insurance industry and call centre areas, but have been called upon to provide many varied solutions.

I'm educated to UK A level standard, but as I left school some 30 years ago that is rather irrelevent - university of life has provided more of a background!
