Show certain values in a textfield based on checkbox input

Question

Hello,

Javascript is not really my cup of tea, so I'm hoping someone here is able to help me out with this problem.. In the form I'm creating, it is needed that a certain value is shown in a certain textfield based on which checkbox is marked. There are 4 checkboxes (CheckBoxWarranty, CheckBoxWarranty1, CheckBoxWarranty2, CheckBoxWarranty3). This is set up in a way that the user only can check 1 checkbox (it is not possible to check multipe checkboxes). But depending on which checkbox is marked, a certain value need to be shown in the textfield Result. Below you'll find a overview of which value that needs to be shown for each checkbox.

CheckBoxWarranty = 10

CheckBoxWarranty1 = 12

CheckBoxWarranty2 = 15

CheckBoxWarranty3 = 20

Based on other discussions, I was already able to make this work for 1 checkbox with the following code as a custom calculation script for the textfield.

event.value = (this.getField("CheckBoxWarranty").valueAsString=="Off")? "" : "10";

But I don't really know how to go further from here. I already tried adding the same lines for the other checkboxes to the code. But tthis result in always showing the results for the first line, I assume the first line simply overwrites the others. I assume this needs some conditional-statements? So some help here would really be appreciated.

Thanks in advance.

You could do it with export value, but it would need to be set correctly,
but it's easier to put values in a script, if you know all the values for each checkbox,
you can put them in an array and then use the loop to populate fields (years)
with correct value.
Since you didn't provide field names or values let's say you put export value for checkboxes to be 1 for 1st checkbox, 2 for 2nd, 3 for 3rd and 4 for 4th, and let's say you have 20 fields named "Year1" to "Year20"
you can use this script in any text field as custom calculation script, only input your values in arrays 'check1' to 'check4':

var check1 = [10, 20, 30, 40];
var check2 = [5, 15, 23];
var check3 = [1, 2, 3, 4, 5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20];
var check4 = [9, 12, 18, 122];

for (var i=0; i<20; i++) {
var c = this.getField("CheckBoxWarranty").valueAsString;
var year = this.getField("Year" + (i + 1));
    
if (c == "1" && i < check1.length) {
 year.value = check1[i];} 
else if (c == "2" && i < check2.length) {
 year.value = check2[i];} 
else if (c == "3" && i < check3.length) {
 year.value = check3[i];} 
else if (c == "4" && i < check4.length) {
 year.value = check4[i];} 
else {
 year.value = "";}}

If you want user to select only one checkbox you need to make checkboxes mutually exclusive by giving all your checkboxes same name (name all 4 checkboxes "CheckBoxWarranty") and set export values of each checkbox to be the number you want, for example give 1st checkbox export value 10, 2nd checkbox, export value 12...etc

In text field, as custom calculation script use this:

var c = this.getField("CheckBoxWarranty").valueAsString;
event.value = (c == "Off") ? "" : c;
