Dunno if this is what you want, but:
<script language="javascript">
function changeIt(select1, select2)
{
if (document.getElementById(select1).selectedIndex > 0)
{
document.getElementById(select2).selectedIndex = 1;
}
}
</script>
<form>
<select id="A" onchange="changeIt('A','B');">
<option>1</option>
<option>2</option>
</select>
<select id="B">
<option selected>A</option>
<option>B</option>
</select>
</form>
Changes the index of B from 0 to 1 if you change the index of A to anything
higher than 0 (1 in this case).
