How do you add the selected value of one combobox to another
I have a form with 2 selects like this:

<form id=&quot;form1&quot;>
<select id=&quot;countries&quot; onChange=&quot;loadCountry()&quot;>
<option value=&quot;France&quot;>France</option>
<option value=&quot;UK&quot;>UK</option>
</select>

<select id=&quot;country&quot;>
</select

the onchange=&quot;loadCountry()&quot; script looks something like
<script>
function loadCountry()
???form1.country.add???? = form1.countries.option(form1.countries.selectedindex).value
end function
</script>

So basically, how do i populate the combobox &quot;country&quot; with UK once i have selected it from countries?
I'm sure this is quite easy, so thanks for your help.
