Excel/Max If Formula


I am stumped on a complex Max If formula. I have data in column CX. I have two dates relating to that data in columns DB and DC (start date, end date). I'd like to use a single formula that looks at both dates and if the weeknum & year of both dates are equal to the current weeknum & year, take the max value of those qualified numbers in row CX. Any guidance is greatly appreciated!


Data in CX

Start Date in DB
End  Date in DC

this is probably what you were looking for -

entered with Ctrl+Shift+Enter.  But that doesn't work because weeknum does not appear to work with mulitple cells as an argument.  Instead, I put in   =weeknum(DB1) in DD1 and =weeknum(DC1) in DE1 and drag filled those formulas down. Then I used the below formula


entered with Ctrl+Shift+Enter and that worked for me.  I am afraid you will have to use added columns otherwise you will have to calculate the end dates for your the current weeknum and put those in your formula instead of trying to use weeknum

QUESTION: I had to rearrange your formula to fit the exact data I'm working with but I'm not getting the correct result. I'm not sure if the data I plugged in compromised the formula...Is there something wrong with my formula:

Named Range of Data to find Max value: WinStreak
Named Range of Dates to match: WinStreakStartDate, WinStreakEndDate
Named Range to refer to today's date in code: Today ie:(DAY(TODAY() & MONTH(TODAY() & YEAR(TODAY())

Formula to find max value in 'WinStreak' if the two dates equal the the value of 'Today'



If you have dates in the columns WinStreakStartDate, WinStreakEndDate

So the criteria would be that today is greater than or equal to the startdate in that row and less than or equal to the enddate for that row - then consider the value in winstreak for that row.  The formua for that would be:


Entered with Ctrl+Shift+enter

assume the named range Today is a single cell.  

also, my original formula appears screwed up and not sure why - I may have copied the wrong formula.  


should have been

entered with Ctrl+Shift+enter.  Anyway, you are not using that formula, but just for completeness.
