Manage Inputs & Outputs
Use this tool to add or delete input and output variables to or from the worksheet you are analyzing.

Add and delete input variables

To delete, for example, the input variable called Cost of Goods Sold from the worksheet you are analyzing,
click on the Load Inputs button. Then choose this variable from the list. As you press the Delete Item button,
the selected variable will be eliminated with its corresponding table of values.
Now, to add an input variable to your worksheet, do as follows:

Click on the Load Inputs button and select the input variable you want to add (in this example, select the cell in your
model you want to add to the scenarios sheet to analyze it), then click on the Add Item button. As you can see, the selected input variable
Notice that the selected input variable is added to your scenarios sheet.

In this example the Manufacturer input value has been added.
Then you can add the possible values of this new input variable and run the tool again to analyze
how they affect the Gross Margin, your output variable

Add and delete output variables
To add and delete output variables, just click on the Load Output
button and select the variable you want to delete from the list,
or click on the Add item button to add an output variable.

WARNING
Always use the Manage Inputs and Outputs tool to add and delete input and output variables. Although you can
indeed do such operations manually, doing so will bring about unexpected results in you worksheet, since
the Add-In validates data using VBA code.
Do not add more than 20 input variables, the maximum number of variables supported by this tool.
Input value tables should not have over 20 alternatives; doing otherwise will result in errors in the worksheet.
If you alter any formulas unintentionally, please see how they are designed in other cells and correct them manually.
