Code that shows mouse events
HTML
<div onmousemove="showCoords(event)" onmousemove="why()" onmouseout="clearCoor()">
</div>

<p id="demo"></p>
JavaScript
function showCoords(event) 
{
  var x = event.clientX;
  var y = event.clientY;
  var coor = "X coords: " + x + ", Y coords: " + y;
  document.getElementById("demo").innerHTML = coor;     
}

function clearCoor() 
{
  document.getElementById("demo").innerHTML = "";
}

function why(event) 
{
  var x = event.clientX;
  var y = event.clientY;
  if ((x == '40') && (y =='40'))
  {
    document.getElementById("what").innerHTML = "Wow";
  } 
}

function why() does not do what it should which is display message

1. Include the relevant parts of your code in your question. Do not simply link to another site with all of your code and expect people to visit it and dig through to find the problem.

2. Your question says the function wow doesn't do what it should. But there is no such function in your sample.

Where is the code for function wow?

You need to put your onmousemove in the body tag as shown in the sample link above:
<body onmousemove="why(event)" onmouseout="clearCoor()">

You also need to check the actual names you are using in the id fields of your HTML. What you have is inconsistent. A few simple corrections and your code works (sort of).

the function is why; its raining here

I have no idea what that means, or what relevance it has to your question.

This sort of works, so you can build on it yourself:
JavaScript
<!DOCTYPE html>
<html>
<head>
</head>

<body onmousemove="showCoords(event)" onmouseout="clearCoor()">
<script type="application/javascript">

  function showCoords(event) {
    var x = event.clientX;
    var y = event.clientY;
    var coor = "X coords: " + x + ", Y coords: " + y;
    document.getElementById("what").innerHTML = coor;
  }

  function clearCoor() {
    document.getElementById("what").innerHTML = "";
  }

</script>

<h2>A simple Javascript test</h2>

<p id="what">this is what</p>


</body>
</html>
