javascript code trouble with dialog box Adobe Acrobat

Thank you too for your effort and the time you took to respond to my post. II tried but without success 😞

var FormSelect = {
  result: "cancel",
  doDialog: function() {
    return app.execDialog(this);
  },
  bChk1: false,
  bChk2: false,
  bChk3: false,
  initialize: function(dialog) {
    dialog.load({
      Chk1: this.bChk1,
      Chk2: this.bChk2,
      Chk3: this.bChk3,
    });
  },
  commit: function(dialog) {
    var oRslt = dialog.store();
    this.bChk1 = oRslt.Chk1;
    this.bChk2 = oRslt.Chk2;
    this.bChk3 = oRslt.Chk3;
  },
};

Thank you for your effort and the time you took to respond to my post. Unfortunately I am not able to fix it ☹, since I am not a programmer, I can not also to fix it also using Google, search in the forums etc. Actually, I am willing to make a small donation with PayPal if someone would correct this code for me. Next step would be categories and subcategories. The selected Checkbox values should be returned or printed into the text field "Documents".

For Example:

1. under Personality "Your Name", "Your Country"

2. under Hobbies "Sport", "Cinema"

3. and so on...

I'm doing it for my friend, since I promised him I would create this form, even though I'm not able to. He actually has all these items in a list box that can be selected on each line. But I wanted to do it with a dialog box since I downloaded your sample file here https://acrobatusers.com/tutorials/popup_windows_part5/ 

I have also modified my code a little bit as below and I got errors:

TypeError: dialog.getField is not a functionMakeChoices.commit@Field:Mouse Up:13

      "Chk2": this.bChk2
    };
    dialog.load(dlgInit);
  },
  commit: function(dialog) {
    var thisForm = dialog.getField(this.name);
    var oRslt = dialog.store();
    this.bChk1 = oRslt["Chk1"];
    this.bChk2 = oRslt["Chk2"];

    // Create a list of selected checkboxes
    var selectedValues = [];
    if (this.bChk1) selectedValues.push("Your ID Card");
    if (this.bChk2) selectedValues.push("Your Name");

    // Set the value of the "Documents" text field to the selected values
    var field = thisForm.getField("Documents");
    if (field) {
      field.value = selectedValues.join(", ");
    }
  },
  DoDialog: function() {
    return app.execDialog(this);
  },
