Below is a mock example of my spreadsheet.

Column B has the names of Tutors who deliver training hours to the Students listed in Column A. And Colums C1:I1 have all the dates for every month (showing is just 23Jan-31Jan).

I need a formula to give me the underlined answers in the below sample SS (e.g. I need to add up all training hours for each Tutor between 2 dates, and I need these two dates to be able to be changed).

</tbody>[/TABLE]

The 2 most promising formulas I have are these:


=SUMIFS('SS#1'!C1:I1,'SS#1'!B:B,B2,'SS#1'!C1:I1,">="&'SS#2'!B1,'SS#2'!C1:I1,"<="&C1
which gives me a #VALUE error

And:


=SUMPRODUCT(--('SS#1'!C1:I1>='SS#2'!B1)*('SS#1'!C1:I1<='SS#2'!C1)*('SS#1'!B:B=B2))

This 'works' however gives me a value of 0 so something isn't working there... Does anyone have any ideas? :(
 

Excel Facts

Can you AutoAverage in Excel?
There is a drop-down next to the AutoSum symbol. Open the drop-down to choose AVERAGE, COUNT, MAX, or MIN
Maybe something like this:

Thank you so much! Glad it was actually something 'simple'. Annoying it doesn't work across different spreadsheets/worksheets but hey, at least there's a version that works!
