1) it works if you put the script in the html:
<html>
<head><title></title></head>
<body></body>
<script>YOUR CODE HERE...</script>
</html>
2) you have bad references in the variables, because you declare a variable into a function but you want to use in another function where the variable doesn't exists. You need to declare outside the function:
You have this:
function x{
  var example = 1;
}  
function y{
  example = 2;
} 
but the function Y doesn't know what is "example" 
So you need to declare outside the function:
var example = 1;
function x{
  example++;
} 
function y{
  example++;
}
