Javascript – using form input value within a modal

I keep getting this error: Uncaught TypeError: Cannot set properties of null (setting ‘innerHTML’)

or: Uncaught TypeError: Cannot set properties of null (setting ‘textContent’)

When trying to change the text of an anchor tag after a modal opens.

Here’s the modal:

 <!-- Success Modal -->
    <div class="modal-container" id="modal">
        <div class="modal-main">
            <img
                src="./assets/images/icon-success.svg"
                alt="success image"
            />
            <h1 class="modal-header">Thanks for subscribing!</h1>
            <p>
                A confirmation email has been sent to
                <a href="#" id="modal-email">test</a>. Please open it and
                click the button inside to confirm your subscription.
               
            </p>
        </div>
        <button id="dismiss-btn">Dismiss message</button>
    </div>

The Form:

   <form id="form">
            <label for="email">Email address</label>
            <input
                type="email"
                name="email"
                id="email"
                placeholder="[email protected]"
            />
            <button id="button">Subscribe to monthly newsletter</button>
        </form>

and the Javascript:

const form = document.getElementById("form");
const btn = document.getElementById("button");
const dismissBtn = document.getElementById("dismiss-btn");
const modal = document.getElementById("modal");
const modelEmail = document.getElementById("model-email");

form.addEventListener("submit", function (e) {
    e.preventDefault();
    modal.style.display = "block";

    let formData = new FormData(this);
    let inputValue = formData.get("email");

    console.log(inputValue);
    modelEmail.textContent = "example";
});

dismissBtn.onclick = function () {
    modal.style.display = "none";
};

The correct value appears in the console when console logging the inputValue, but I keep getting errors when trying to change the textContent of the anchor tag in the modal. Whether I use the inputValue or [in this case] the string of “example”, I keep getting the null error.
