Reference fields

You can use an existing field as the basis for the expression. A reference field gets the value of the field for each occurence in the table. Follow these steps to select a reference field:

1. Locate the Reference field in the Contants list of the Logic blocks.

2. Drag and drop the Reference field to the applicable logic block on the canvas.

3. Select the logic block on the canvas to open the properties, then select the field you want to use in your expression.

The reference field is displayed in the logic block and you can use it for further calculations.
