After adding a button line to enable a clock in HTML and the corresponding function in a <script> tag (which may or may not work), suddenly all functions on the page become undefined. There is only one other function on that page, so it could be causing the issue. I've spent some time looking for syntax errors but haven't been able to find anything.
The order of elements on the page should follow JavaScript, then CSS, then HTML.
function startTime() {
var today = new Date();
var h = today.getHours();
var m = today.getMinutes();
var s = today.getSeconds();
m = checkTime(m);
s = checkTime(s);
document.getElementById('txt').innerHTML =
h + ":" + m + ":" + s;
var t = setTimeout(startTime, 500);
}
function checkTime(i) {
if (i < 10) {i = "0" + i};
return i;
