Answer 1

you had a jquery error in line 259.
but I see that you fixed it

Answer 2

Justtt Fixed It
Before I was using document.getElementById ("id").innerHTML = value

However that produces a null error here but not in usual browsers

While going through the JQuery Course However

I noticed I can do

$("#id").html (value)

Which works like a charm
