document.fm.name.focus() not working in IE

I added this javascript in my page to make it first focus on the input box which is named "name".

<script language="javascript">
document.fm.name.focus();
</script>

It's working in Firefox, but not working in Internet Explorer. What's the problem?

 

Actually it should work. You may try by some other method like
document. getElementById(id-of-element).focus();
