Splitting up a date field into two fields on display

Question

I have a form that is based on a table which contains two date fields. To populate these date fields I have one date picker using a format of DD-MON-YYYY and two "time" fields that are just based on static LOV select lists. I build the date by piecing together these fields to get my two different dates and save it to the database just fine (using a process on submit, before validation).
My problem comes when I want to edit the existing records. I am unable to figure out how to populate those fields from the dates. I thought I could do it during the page reduring process but everything I try gives me a format error. I can assign the date to the date picker field no problem but cannot get it to display without the date format, regardless of setting the format or not on the item. I can't get the time off into my time fields at all.
An example of setting my start time field (select list of times only)
BEGIN
:P10_START_TIME := TO_CHAR(:P10_DTE_START,'HH24:MI');
END;
Error I get is ORA-06502: PL/SQL: numeric or value error: character to number conversion error
I've tried a few different formats and I think I am just missing something really easy. My static pick list in this case is just the display would be say 1:00 PM but the other value is 13:00.
The other one I am trying is for the actual date picker itself.
BEGIN
:P10_COURSE_DATE := TO_DATE(:P10_DTE_START, 'DD-MON-YYYY');
END;
Gives me ORA-01830: date format picture ends before converting entire input string.
The format of :P10_DTE_START is DD-MON-YYYY HH24:MI (it is a hidden field) and :P10_COURSE_DATE is DD-MON-YYYY.
Colour me confused...

Answer 1

Thanks for the reply...I got this error for the last name piece "A subscript must be between 1 and the size of the array.
". I was able to put in
split({Usr.Nam}, " ")[-1]
and that seemed to pull  the last name piece of the field.
Thanks Again,
