You can assign values or a range of values to the parameters.
                  Each column corresponds to a parameter and each row to a part of the formula. Each cell contains a  value or a range of values allowed on the row for the parameter. Between the formulas of each cell on the same row there is an "And" operator. 
    	
    
      - 
          Select any cells of the parameter to which you want to assign a value or a range of
            values to create the formula. 
          The  Value Editor area lets you select the values
            available for the parameter. You can select: 
              - A range of value or a value if the selected parameter is a numerical one. 
- A single value if the selected parameter is not a numerical one.
- "Any value" if you consider that the parameter is not important for this part of
                the formula. 
 Note:
    		You do not have to confirm your choice, the app integrates it
              immediately and displays it in the appropriate cell. 
- Select one or more values. If the parameter is a numerical one, you can click the  -∞ and +∞    symbols to use an infinite range.
- Repeat the operation as many times as needed.

            Click Finish.
          
           The formula is created. 
 
 Because the formula has been defined, the filter unit is created. You can view the
        results as explained in View the Filtered Parts.
