Answer 1

The following code works for me:
<script language="JavaScript" type="text/javascript">
function hide()
var rv = html_RadioValue('P4_RATE');
if (rv == 1)
$x_HideItemRow('P4_FRIEGHT_TYPE');
else
$x_ShowItemRow('P4_FRIEGHT_TYPE');
</script>
Replace the 1 in if (rv == 1) by the value in your static list.
