Answer 1

This error actually happens alot. Your code is correct, but you have to include this in the Javascript tab:
window.onload = function()
{
//place your code here
}
This is needed because otherwise, the Javascript code will run before the HTML, and an error will be returned since "amount" doesn't exist yet.
