Hi, it is actually not difficult.
Here is a piece of old examplecode to get you going:

<html>
<head>
<title> titel </title>
<script type="text/javascript">

function setme(num)
{
document.forms. aform.fruit.sel ectedIndex = num;
}

</script>
</head>

<body>

<form name="aform">

<select name="fruit">
<option value="bananas" >bananas</option>
<option value="kokos">k okos</option>
<option value="apple">a pple</option>
</select>
<input type=submit >
</form>

<p>
<a href="javascrip t:setme(0);">se t bananas</a><p>
<a href="javascrip t:setme(1);">se t kokos</a><p>
<a href="javascrip t:setme(2);">se t apple</a><p>
</body>
</html>
