Counting empty text fields

Hi. I'm looking for a way to count empty text fields in a pdf form and to have the result automatically entered in another field on the same form. Thanks in advance for your help.

    What type of fields do you want to check, exactly? Checking for an unchecked check box or radio button is done differently than checking for a blank text field, which is different than an apparently blank combobox/dropdown.

    It is a simple text field where the user has the option of entering a numerical value, or not. It is not a combobox or dropdown. When the user does not enter a number, that empty field needs to be counted.

    OK, here's a simple custom calculate script for a text field that displays the number of blank text fields that are named "num.1" - "num.10":

     

    // Custom Calculate script
(function () {

    // Initialize sum of blank fields
    var sum = 0;

    // Count how many fields are blank
    for (var i = 1; i < 11; i += 1) {
        if (!getField("num." + i).valueAsString) sum += 1;
    }

    // Set this field value to the sum
    event.value = sum;

})();
