==To Remove All Options Except the Selected==
* The following script will prevent users from changing the Level 2 Type once the record has been saved:
<pre>
// For existing Types remove all options from the Type field (except the selected) so it can't be changed
if (frm.eventid.value!=0)
{
for (i=frm.eventtype.options.length-1;i>=0;i--)
{
if (frm.eventtype.options[i].value!=frm.eventtype.value)
frm.eventtype.options[i]=null;
}
}
</pre>
