how to identify
how to identify a few cells in a list(A1) that sums a equal total in another
cell(B1) i.e: A1 --- 1,245.55 34,543.68* 8,955.67* 43,873.93 11,282.08* B1 --- 54,781.43 thanks in advance. -- sarans |

You could try using solver. I haven't done this in many years so I
don't remember the specifics. I think I set up a column adjacent to my list of numbers. In the second column, I entered the number 1. I then used =SumProduct(ColA:ColB) which equalled the sum of all numbers (since they were multiplied by one.) I then used Solver to "play" with the column of 1's setting some of them to zero until the formula equalled the target value. - John |

how to identify
Hi sarans:
With only 5 numbers, John's approach can be applied withou solver: 1. enter you values into A1 thru E1 and copy down to row 32. 2. enter the following table in F1 thru J32: 0 0 0 0 0 0 0 0 0 1 0 0 0 1 0 0 0 0 1 1 0 0 1 0 0 0 0 1 0 1 0 0 1 1 0 0 0 1 1 1 0 1 0 0 0 0 1 0 0 1 0 1 0 1 0 0 1 0 1 1 0 1 1 0 0 0 1 1 0 1 0 1 1 1 0 0 1 1 1 1 1 0 0 0 0 1 0 0 0 1 1 0 0 1 0 1 0 0 1 1 1 0 1 0 0 1 0 1 0 1 1 0 1 1 0 1 0 1 1 1 1 1 0 0 0 1 1 0 0 1 1 1 0 1 0 1 1 0 1 1 1 1 1 0 0 1 1 1 0 1 1 1 1 1 0 1 1 1 1 1 3. in K1 enter: =SUMPRODUCT(A1:E1,F1:J1) and copy down. Just pick the correct value out of column K -- Gary's Student "sarans" wrote: how to identify a few cells in a list(A1) that sums a equal total in another cell(B1) i.e: A1 --- 1,245.55 34,543.68* 8,955.67* 43,873.93 11,282.08* B1 --- 54,781.43 thanks in advance. -- sarans |

Hi John
Thanks for your post. I couldn't get the correct result. Could you please place an example. -- sarans "John Michl" wrote: You could try using solver.

Hi Gary's Master
Yes, it works. Thanks a lot. You are great. I still need to figure out John's approach too.

In cell A1 through A5, enter the five numbers.
In cell B1 through B5, enter 0 (zero) In cell B6 enter =SumProduct(A1:A5,B1:B5) Choose from the menu, Tools Solver Set Target Cell to B6 Equal to Value of 54,781.43 By Changing Cells B1:B5 Subject to the Constraint B1:B5 = binary Click Solve and those values that are part of the answer will show a "1" next to them. - John |

A minor modification that will make it more useful. Instead of
entering the target number in solver, enter in the spreadsheet. To continue the above example, A7 = Target Value A8 = Variance B7 = 54,781.43 B8 = abs(b6-b7) In solver change "Equal to Value" to "Equal to Min" then solve. When done, if the Variance is zero, you'll have an exact match. If it is not zero, then you'll have the combination that is closest to the target as possible. - John www.JohnMichl.com |

Hi John
Thank you very much for your prompt response. I will try later as I am out at this time. Best regards, -- sarans "John Michl" wrote: A minor modification that will make it more useful.
