Excel Facts

Last used cell?
Press Ctrl+End to move to what Excel thinks is the last used cell.
A way to do
Assuming data in row 1 from A to G
Put 0 in row 2 from A to G
In H3 put =SUMPRODUCT(A1:G1*A2:G2)

Call (or install first) the solver
Set target H3
Equal to your value 36
by changing cells A2:G2
Subject to the Constraints
A2:G2 = binary
Add
OK

Excel stops when one possibiliy is found, if you change the daata order result will change
If you want all possibilties it is another story and need a macro .
