For some reason, my code is throwing a TypeError, and I cannot seem to grasp the problem.

<h1>MCPE Server Check</h1>
<p>Server IP: <input id="ip-input"></p>
<p>ecpehub.net</p>

<p>Server Port: <input id="port-input"></p>

</html>
JS:
var btn = document.getElementById("btn");
var inputIP = document.getElementById("ip-input").value;
var serverPort = document.getElementById("port-input").value;
var reqURL = "https://use.gameapis.net/mcpe/query/extensive/" + inputIP + ":" + serverPort;
btn.addEventListener('click', loadDoc);
function loadDoc() {
var xhttp;
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (this.readyState == 4 && this.status == 200) {
var info = JSON.parse(xhttp.responseText);
//console.log(info);
document.getElementById("server-ip").innerHTML = info.hostname;
document.getElementById("server-port").innerHTML = info.port;
document.getElementById("game").innerHTML = info.game_name;
document.getElementById("online").innerHTML = info.players.online;
document.getElementById("players").innerHTML = info.players.max;
}
};
xhttp.open("GET", reqURL, true);
xhttp.send();
}
For some reason I am getting a TypeError at var inputIP = document.getElementById("ip-input").value; saying “Cannot read property ‘value’ of null”.
