Hi Sophie,
Do you mean that you are unable to type data into the cell of that you set as Objective?
For example, you set the value in B8 as objective, but you can't enter data into cell B8 when the Solver is opened.
If so, I'd like to explain that we need to close the Solver parameters if we want to enter data into the cell that we set as objective.
Or do you mean that you are unable to enter data into the box next to "Value of" when it is selected?
If so, please try disabling Solver add-in, then restart you Excel and enable it to check the outcome.
If you cannot type data into the box next to "value of" after you do this, I would like to confirm some information to better understand your situation:
- Does this happen to one specific file or all file? Please try creating a new workbook and check whether you can enter data into the box next to "Value of".
- Can you type data if you select Max and Min?
- A screenshot of your table including the Solver Parameters page to let us see the symptom.
- Does this happen previously?
- Your Excel version from Excel menu>About Excel.
For your reference: Example of a Solver evaluation.
Regards,
Joanne
