Calling javascript function on onMouseOut

I wrote the following code, for marquee: In which I want on mouse-over, a function will get called

<marquee class="smooth_m" behavior="scroll" direction="left" scrollamount="3">
  <span style="float:left; padding:0 20px 0 0;" onMouseOut="loadStart()" onMouseOver="loadStop()">testing</span>
</marquee>
<script type="text/javascript">
loadStop()
{
alert("loadStop");  
}
loadStart()
{
alert("loadStart"); 
}
</script>

but it's not loading the respective functions in span like, onMouseOut it should load loadStart and so on.. Can someone help in this?

Solution

Working demo http://jsfiddle.net/CTQVr/ or on mouse over stop marquee like this: http://jsfiddle.net/CTQVr/4/

issues was: function missing from your function name.

Hope this helps,

HTML

<marquee class="smooth_m" behavior="scroll" direction="left" scrollamount="3">
  <span style="float:left; padding:0 20px 0 0;" onmouseout="loadStart()" onmouseover="loadStop()"> testing</span>
</marquee>

jquery code

function loadStop() {
    alert("loadStop");
}

function loadStart() {
    alert("loadStart");
}

Update to stop on mouseover

$("marquee").hover(function () { 
    this.stop();
   // loadStop();
}, function () {
    this.start();
   // alert("loadStart");
});
