User input in forms

G'day,
This problem is best explained using an example: A user has just made some changes to the form. She presses Commit/Accept. What I want to happen now is for Oracle to display a pop-up screen which says "Press <key> to commit, any other key to ignore changes". I've got the pop-up Screen working (It'd be a problem if I couldn't do *THAT*), but what I can't get working is the user input i.e. How do I get the value the user enters ? Cheers,
Rocky.

P.S. thanks to all those that helped me with my update problem. Solution was to remove my SQL update code & just do a commit. Easy!
