alert('sometext');
}
function getScore() {

alert("sometext");
alert('sometext');
var inputs = document.querySelectorAll("input");
for (int i = 0; i < inputs; i++) {
if (inputs[i].type == "radio" && inputs[i].checked && inputs[i].value == "correct") {
score += 1;

var userInputString = inputs[i].value;
var correctAnswer = inputs[i].getAttribute('data-correct');
if (userInputString != null && correctAnswer != null) {
