Adding calculations to your form design

You will make a form more interactive by adding a calculation to your form design. You add JavaScript by using the Script Editor to calculate the mortgage amount in your form design.

Note:   You may need to drag the bottom of the Forms toolbar to expand the area for the Script Editor.

To add a calculation to the mortgage amount:

1. In the Hierarchy palette, select Mortgage.
2. In the Script Editor, select the appropriate options:
   • In the Show list, select calculate.
   • In the Language list, select JavaScript.
   • In the Run At list, select the default Client.
3. In the Script Source field, type the following calculation:

   if (PropertyPrice.rawValue > DownPayment.rawValue)
   {
   
   this.rawValue = PropertyPrice.rawValue - DownPayment.rawValue;
   
   }
   else 
   {
   
   this.rawValue = 0;
   
   }
   

4. In the Script Editor, click Check Script to ensure that there are no syntax errors.
5. Save your form design.

You have added a calculation to the Mortgage field.

You have finished the form design. The following illustration shows how your form looks in Design View.
