IE tells me there's an error on line 17, which is the onload method of the body tag. So here's the code...
<script language="javascript" type="application/javascript">
function startUp() {
setFocus();
}
function setFocus(){
document.frmSearch.txtSearch.focus();
document.frmSearch.txtSearch.select();
}
</script>
And here's how it's called:
<body onload="startUp();">
I tested this in Safari, Firefox, IE 8, Opera, and Chrome. Works in all except IE 8.
