Integrating ASP W/ JavaScript In Form

I am trying to load a dropdown select on an HTML form with the user's current selection based on previous user input that they put into a database. I am trying to use JavaScript to have the user's choice selected when the page loads. Here is my javascript function:
(Assume the database connection code is already in place and functional)

<script language = "Javascript">
function chosen(dropdown){
combobox.option.selected = '<%=rs.fields("State")%>';
return true;
}
</script>
