Почему не открывается второе модальное окно?

<a id="myBtn"><img src="img/low1.png"></a>
					<div id="myModal" class="modal">
						<div  class="modal-content">
                                               <span class="close"></span>

                                                </div>
                                        </div>

var modal = document.getElementById('myModal');
var btn = document.getElementById("myBtn");
var span = document.getElementsByClassName("close")[0];

btn.onclick = function () {
	modal.style.display = "block";
}
span.onclick = function () {

window.onclick = function(event) {

	}
}
