In article ,
says... How do I add a constraint which limits the sum of a range ie I have 2000 leaflets to split between 3 mailshots. I have tried sum(C1:C3)<=2000 but just get nonsense as answer What does "just get nonsense" mean? One of the things to try is in C4 add the formula =SUM(C1:C3). Then, in Solver, specify C4 <= 2000 -- Regards, Tushar Mehta www.tushar-mehta.com Excel, PowerPoint, and VBA add-ins, tutorials Custom MS Office productivity solutions |
