On console showing Javascript error

I am using the Give Wp plugin for donations on the website. I have created a form to add two email IDs now I am trying to validate two email IDs one for a confirmation email. When I use javascript code for validation it’s not triggering anything i removed my custom. When I checked on the console it’s showing an error from the donation form.

I need help resolving this console error so that I can add my custom js

Here is the error code: I think some issue with the donation iframe.

caught ReferenceError: jqueryParams is not defined
at donations-2-3-2-3-2-2-2?giveDonationFormInIframe=1:23:1

My custom js:

document.addEventListener("DOMContentLoaded", function () {

?
? var emailInput = document.querySelector("#give-email");

? var confirmEmailInput = document.querySelector("#give-donor_email-253169-2");

? if (confirmEmailInput) {

? ? emailInput.addEventListener("input", function () {

? ? ? if (confirmEmailInput.value !== emailInput.value) {

? ? ? ? document.getElementById("give-email").style.borderColor = "red";

? ? ? ? emailInput.setCustomValidity("Email Not matched");

? ? ? } else {

? ? ? ? document.getElementById("give-email").style.borderColor = "green";

? ? ? ? emailInput.setCustomValidity("");

? ? ? }

? ? });

? ? confirmEmailInput.addEventListener("input", function () {

? ? ? if (confirmEmailInput.value !== emailInput.value) {

? ? ? ? document.getElementById("give-email").style.borderColor = "red";

? ? ? ? emailInput.setCustomValidity("Email Not matched");

? ? ? ? // emailInput.setCustomValidity("");

? ? ? } else {

? ? ? ? document.getElementById("give-email").style.borderColor = "green";

? ? ? ? //document.getElementById("give-first").style.borderColor = "green";

? ? ? ? emailInput.setCustomValidity("");

? ? ? }

? ? });

? ? var form = document.querySelector(".give-form-253169");

? ? var donateButton = document.querySelector("#give-purchase-button");

? ? donateButton.addEventListener("click", function (event) {

? ? ? event.preventDefault();

? ? ? validateForm();

? ? });

? ? function validateForm() {

? ? ? var firstNameInput = document.querySelector("#give-first");

? ? ? var lastNameInput = document.querySelector("#give-last");

? ? ? var emailInput = document.querySelector("#give-email");

? ? ? var confirmEmailInput = document.querySelector("#give-first");

? ? ? if (emailInput.value !== confirmEmailInput.value) {

? ? ? ? //confirmEmailInput.setCustomValidity("Email addresses must matcSDasdadsh.");

? ? ? ? alert("Email not matched");

? ? ? ? document.getElementById("give-email").style.borderColor = "red";

? ? ? ? return false;

? ? ? } else {

? ? ? ? // confirmEmailInput.setCustomValidity("");

? ? ? ? document.getElementById("give-email").style.borderColor = "green";

? ? ? }

? ? ? // If all validations pass, submit the form

? ? ? document.querySelector(".give-form-253169").submit();

? ? }

? }

});
