You can try something like the following

Code:

<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<style type="text/css">
.menutitle{
cursor:pointer;
margin-bottom: 5px;
background-color:#ECECFF;
color:#000000;
width:140px;
padding:2px;
text-align:center;
font-weight:bold;
/*/*/border:1px solid #000000;/* */
}

.submenu{
margin-bottom: 0.5em;
}

.test
{
	border:1px solid #000;
	padding:2px 2px 2px 2px;
	background-color:#A6CAF0
}
</style>

Thanks for the info I'll have a try at implimenting it.. One question before I do however. Do I copy this code for code or am I meant to insert variable elements myself?.. and if so where.. I was guessing between the "" for example:

var globalObj = "";

Any further clarification would be appreciated .

cheers
