Having trouble getting the sumif function to work.
I have tried 2 versions, below 
=SUMIFS([Days Open]:[Days Open], Location:Location, [Repair Description]17)
=SUMIF(Location:Location, [Repair Description]15, [Days Open]:[Days Open])
The [Days Open] is a number calculated by subtracting 2 dates (the cells with functions)
The [Location] is an address
And the [Repair Description]15 - is just a reference to a cell that houses the address that is being searched for.
Note: when I input the actual (number) of days and and not have it calculate the formula above works...so it seems like the SUMIF function just will not calculate when functions are present.
 
Ultimately i'm trying to get the sum of the open days for a particular address...
Thanks,
