In Revu, you can create form fields that support simple calculation formulas. In this article, we cover how to set up simple calculation fields for your PDF forms.

Add calculation fields to forms

In the Form Properties panel, the Calculate property of a form field is set to Value is Not Calculated by default. You can change this property to Calculation Field to generate sums (+), products (x), averages, minimums, and maximums from form input.

A common calculation is Quantity x Price = Total. To create these calculation fields for your form, follow these steps:

  1. Open a new PDF or an existing form in Revu.
  2. Go to Tools > Form > Text Box.
  3. Click-and-drag a text box on your PDF form.
  4. Repeat steps 2 and 3 to create three text boxes total.
  5. From the Forms panel (Alt+Q), change the name of the first text box (Text1) to Quantity.
    You can also right-click the first text box and select Properties to update the name from the Form Field Properties panel.
  6. Rename the second text box (Text2) as Price.
  7. Rename the third text box (Text3) as Total.
