Hi,

You can use the Solver tool, however, there are often multiple solutions to
this kind of problem and Solver only returns one result.

Consider
1
2
3
4
5
6
If the total I have is 7 what combination of numbers will give that result?
1+6
or
2+5
or
3+4
or
1+2+4
.....

of cells. For example cells filled in with numbers A:A100 and I need to
know
how excel can identify the cells who can be sum to reach a fixed number.
