Show/Hide NON-DB field in a form

Question

Hello, I've been reading all these forums about how to hide or show form fields dynamically. Here's my situation. I have a form that updates to a table Project. By default, once a user submits this form, certain groups will be notified that a new project exists. However, we want certain users (ITSUSERS) to be able to bypass this alert. I have added a checkbox field (SKIPHD) to my form. It does not pull any information from any table. I am planning to program the behavior I want for this checkbox into the doInsert. However, I do not want this option to be visible to any non- ITSUSERS. I am working with this code from another forum member, but I'm thinking it won't work, since this is a non-database field:
declare
cUserid varchar2(30);
cSecrGroup varchar2(30);
iSec number;
begin
cUserid:=portal.wwctx_api.get_user;
cSecrGroup := 'ITSUSERS';
select count(*) into iSec from person_ctl_syn where person_username=cUserid and person_secr_group_code='cSecrGroup';
If iSec = 1 then
htp.p('<SCRIPT LANGUAGE="JavaScript">
function get_index(p_name) {
var x;
for (x=1; x<document.forms[0].length; x++){
if ( document.forms[0].elements[x].name == p_name) {
return x;
var j = get_index("NEW_REQUEST_FORM.DEFAULT.SKIPHD.01");
document.forms[0].elements[j].style.visibility="hidden";
</SCRIPT>');
End If;
end;
This is a really big project I'm working on. I need help!

Answer 1

To add to my previous problem, I'd also like (and this might be impossible for a javascript newbie like me) that when one check box is selected, another becomes visible... within the same form. I will have two checkboxes, one is SKIPHD as mentioned before and the other in SKIPNOTIFY. SKIPHD and SKIPNOTIFY should only be visible to ITSUSERS, but SKIPNOTIFY should also only be selectable if SKIPHD is selected. Possible?
