Required checkbox: disable possibility to save/print + codependente checkboxes?

Question

So I'm completely new to this so bear with me... I also tried searching here for what I need and the closest I could get was this post:
Solucionado: Enforcing required text fields in pdf before savin... - Adobe Community - 3237090

I have to check boxes, one for Yes other for No. I want that both are required unles one of them has been check (so, if you check Yes, No stops being required and viceversa). Is this possible?
The next thing I need is that one or more required fields havent been filled, it not posible to save the doccument or print it. The linked post apparently does that, but again, being new I have no idea what any of the script or whatever mean. Starting with the fact my adobe is in Spanish and I can't find anything that would ressemble the "onBlur" action.

The boxes are named Check Box3 (yes) and Check Box4 (no)

The most I was able to do was "this.getField("Check Box4").required = false;" : that only sets as not required NO if I checked YES; now i need the code that resets the required values accordingly.

Ty in advance!

@Nesa Nurani Ty again! Oh, how would that script be? I tried asking ChatGPT and got this, but its not working. What is missing?

this.dirty = false; 
var requiredFields = ["Check Box3", "Check Box4"]; 

for (var i = 0; i < requiredFields.length; i++) {
    var field = this.getField(requiredFields[i]);
    if (field && field.required && !field.value) {
        app.alert("Por favor, complete todos los campos requeridos antes de guardar.");
        this.dirty = true; 
        break;
    }
}

I used that in "Dcouement will save" action (documento se guardará)

Try something like this:

var requiredFields = ["Check Box3", "Check Box4"]; 
for (var i=0; i<requiredFields.length; i++) {
 var field = this.getField(requiredFields[i]);
 if (field.required === true) {
 app.alert("Por favor, complete todos los campos requeridos antes de guardar."); 
  break;}}

If those are only two fields, you check you can use something simpler like this:

var c3 = this.getField("Check Box3").valueAsString;
var c4 = this.getField("Check Box4").valueAsString;

if(c3 === "Off" && c4 === "Off")
app.alert("Por favor, complete todos los campos requeridos antes de guardar.");

This is not possible. The closest you can get to it is to force the printed copy to contain a visible error message about missing fields, or to force all the fields in it to be empty.

You can achieve either one of those things using this (paid-for) tool I've developed:
