      I dont get with your multiple index, are u looking for something like this...

      Code:
      <html>
	<head>
		<script type="text/javascript">
		   function doThis()
		   {
				var zz= document.getElementById('mySelect1');
				var yy= document.getElementById('mySelect2');
				for(var i=0;i<zz.length;i++)
				{
					if(zz.options[i].selected)
					{
					   //alert(zz.options[i].value);
						var temp = zz.options[i].value;
						for(var j=0;j<yy.length;j++)
						{
							if(yy.options[j].value==temp)
							   yy.options[j].selected="true";
						}
					}
				}
		   }

		</script>
	</head>
	<body>
		<table>
			<tr>
				<td>
					<select id="mySelect1" multiple size="15">
						<option value="option1">option1</option>
						<option value="option2">option2</option>
						<option value="option3">option3</option>
						<option value="option4">option4</option>
						<option value="option5">option5</option>
						<option value="option6">option6</option>
						<option value="option7">option7</option>
						<option value="option8">option8</option>
						<option value="option9">option9</option>
						<option value="option10">option10</option>
						<option value="option11">option11</option>
						<option value="option12">option12</option>
						<option value="option13">option13</option>
						<option value="option14">option14</option>
						<option value="option15">option15</option>
					</select>
				</td>
				<td valign="middle">
					<input type="button" value="highlight" onclick="doThis()">
				</td>
				<td>
					<select id="mySelect2" multiple size="15">
						<option value="option1">option1</option>
						<option value="option2">option2</option>
						<option value="option3">option3</option>
						<option value="option4">option4</option>
						<option value="option5">option5</option>
						<option value="option6">option6</option>
						<option value="option7">option7</option>
						<option value="option8">option8</option>
						<option value="option9">option9</option>
						<option value="option10">option10</option>
						<option value="option11">option11</option>
						<option value="option12">option12</option>
						<option value="option13">option13</option>
						<option value="option14">option14</option>
						<option value="option15">option15</option>
