In the Subject to the Constraints box, enter any constraints that you want to apply by doing the following: You can specify up to 200 variable cells. The variable cells must be related directly or indirectly to the objective cell. Separate the non-adjacent references with commas. In the By Changing Variable Cells box, enter a name or reference for each decision variable cell range. If you want the objective cell to be a certain value, click Value of, and then type the value in the box. If you want the value of the objective cell to be as small as possible, click Min. If you want the value of the objective cell to be as large as possible, click Max.

The objective cell must contain a formula. In the Set Objective box, enter a cell reference or name for the objective cell. Note: If the Solver command or the Analysis group is not available, you need to activate the Solver add-in.
