Form Calculation Dynamic Data Tag fallback when not all fields selected

Hello, I have multiple form fields that calculates final price when each field is selected.

The problem is that

{brf_form_calculation:fkrdj}

shortcode outputs “Please fill all fields”. If not all fields are selected. However, I would like to show at least “0 EUR” until all fields are selected instead of “Please fill all fields”.

Because my final output is like The total amount of project is: Please fill out all fields. EUR

Hey all, solved myself.

All you need is to uncheck “Set empty to 0” checkbox and set “Empty Empty message” below to desired value like: 0.

So now I will have The total amount of project is: 0 EUR until user selects all fields used in calculation formula.
