hello,
i'd like to have the mouse pointer change to a hand when it hovers over the search button of the html search box. i tried this with no luck:

<span onmouseover="this.style.cursor= 'hand'"><input type="submit" value="" style="border-style: none; background: url('images/searchbutton2.gif') no-repeat; width: 24px; height: 20px;"></span>

i know this should be simple but i can't get it to work

thanks.
