Need help in finding out the bug in this javascript to refresh an iframe

    Hello Everyone,
    I am new to writing javascripts. I am working on a web-interface that has to show certain data in real-time (update it every 2 seconds). I figured including an iframe and reloading it with javascript would be the best bet. So to see if it works I wrote this test code. But it doesnt reload the iframe every 2 seconds. Can anyone point out where I am going wrong ?


    this is the code for hello1.php
    <html>
<head>
<script type="text/javascript">
function reloadIt()
{
var frm=document.getElementsByid("iframe1");
frm.src=frm.src;
setTimeout("reloadIt()",1000);
}
</script>
</head>

<body onload="reloadIt()">
<h1>This is a test</h1>
<p>The random integer is 
<iframe id="iframe1" name="iframe1" height="30" width="300" src="hello.php"></iframe>
</p>
</body>
</html>
    PHP:
    and this is the code for hello.php

    <?php 
$i=rand(0,10); 
print ("$i"); 
?>
    PHP:
    Any help with this would be highly appreciated.

    Thanks

    try it this way and it will work. note the correct spelling of getElementById

    <html>

<head>
<script type="text/javascript">

function reloadIt()
{
document.getElementById("iframe1").src="hello.php";
var t=setTimeout("reloadIt()",1000);

}

</script>
</head>

<body onload="reloadIt()">
<h1 id="h1">This is a test 2</h1>
<p>The random integer is
<iframe id="iframe1" name="iframe1" height="30" width="400" src="hello.php"></iframe>
</p>
</body>
</html>
    Code (markup):
