Auto pop alter message - Help needed

Question

Hello Experts,
I need your little help in making the select list editable. Does any of you have any idea?
Please find the following information/details:
I have an appointment page where I need to set an appointment.
So I have 7 fields (same as of my table - Appointments) on my page
Pxx_Start_Date (appointment start date) (date picker)
Pxx_From_Hour (appointment start hour) (select list 00 to 23)
Pxx_From Min (appointment start minutes) (select list 00, 15, 30, 45)
Pxx_End_date (appointment end date) (date picker)
Pxx_End_Hour (appointment end hour) (select list 00 to 23)
Pxx_End_Min (appointment end minutes) (select list 00, 15, 30, 45)
Pxx_Description (appointment description) (text item)
All appointments are stored in Appointments table.
and what I required is:
* to alert (Pop a Message) the user before 15 minutes of the next appointment.*
eg: start_date - 08/12/2009, from_hour - 15, from_min - 30, end_hour - 16, end_min - 00, end_date 08/12/2009 and Description - Apex meeting, room no 1.
So it should alert at 15:15.
Your help would be appreciated. It would be nice if you can put an example with steps on apex.oracle.com.
Kind Regards,

Hi here's a starting idea....
Put this in your HTML Header of the page (or in the page template)
<script>
function alertMe(){
if (document.getElementById('alertMe'))
{alert('Get to your meeting!');
</script>Then put this in the HTML body attribute
onload="alertMe();"Then create an application process On-load like this
BEGIN
htp.p('<div id="alertMe"></div>');
END;Just stick your logic in that application process so if the user is due then do the htp.p, and end if.
Cheers
Ben
