Add a simplified field notation in a PDF file

Simplified field notation is written more like formulas you add in spreadsheet applications like Microsoft Excel. Writing a notation is often an easier solution when adding calculation scripts.

To add a simplified field notation

  1. Open the PDF in Nitro PDF Pro
  2. On the Forms ribbon, in the Form Fields group, click Text FieldForms Field
  3. Select the text field to edit
  4. Right-click and select Properties
    Properties right click Text
  5. Click the Calculate tab
  6. Click the Simplified field notation option, and then click the Edit buttonText Field Properties
