What If Analysis with Script Variable and Parameters

    This is an example of what If Analysis where variables are defined in the script and thanks to some parameters, users can modify them and, then, the final result. Of course, the same variables/expressions could be inserted in the front end (in this example it's a simple calculation - the Return), but sometimes variables used in a What If Analysis, influence huge expressions in a deep level of calculation steps... so they can be placed in front end but the result is a dramatic loss of performance.
