Automatically adding current user and time to textbox

Question

I have a text box called notes on one of my pages and I am wondering if it is possible to automatically add the current user's APP_USER name as well as the current time at the end of what ever the person writes.
For example:
The user writes - "Hello my name is bob." and hits submit
What shows up - "Hello my name is bob. - BOB.SMITH 15-MAR-2013 4:13pm"
Does that make sense? Do you need any more info?
Any help would be appreciated,

Answer 1

B, yes Computation Point: After Submit is what I meant when I said a Computation after submit.
However, the code I provided was for a Process and not a computation. :)
Look at your computation and you'll find that the "Computation Type" says "Static Assignment" with means it will assign exactly what you enter.
Choose one that is appropriate for what you will enter. AND because it's a computation you do not enter the left side of the assignment (i.e. :P1015_NOTES := ...)
So... if you go with for example "PL/SQL Function Body" the code you enter would be:
return :P1015_NOTES || ' - ' || :APP_USER || ' ' || to_char(sysdate, 'DD-MON-YYYY HH:MI PM');APEX will execute the code and assign it to your item.
Hope this helps.
