Dear all - I'm not familiar with accounting jargon but what I need is
this:
say I have a range of different numbers from cell A2 to cell A100. I
need to
establish if any of these cells *ADDED TOGETHER* equal "x". so when I
enter
the no "x" into the formula in cell A102, this will then highlight
which
cells will equal "x".

An example: I need to establish if any cells added together equal 150.
I
put in 150 in the formula. Formula then searches the range A2 to A100
and
highlights cell A27 which contains no.100, and cell A89 which contains
the
no. 50.

Any assistance will be most sincerely appreciated!!

Cheers Bob



To highlight:
Select A2:A100, Formats - Conditional formatting
If the current cell is A2 , then formula is =$B2=1, and choose a
colour


Now use Solver and try the following:

B2:B100 = 0
A102 = SUMPRODUCT(A2:A100,B2:B100)

In Solver, target cell is A102 equals to value of <your target value
by changing cells B2:B100. There should also be another window that
reads "Subject to the contraints". In here add a constraint B2:B100 =
binary. This limit B2:B100 to be either 1 or 0. Run solver.

Here is the catch, if some numbers you know they can appear more than
once, those numbers need to appear more than once in your data (ie.
A2:A100 in the above example). Another catch is that there may be more
than one combination that yields the same target value and solver will
not give you all the results.


Hope it helps
