After a user locks their schedule by selecting "I affirm this statement" in the "Set Schedule Lock" pop-up, it would be nice if there was a success message like "Your schedule has been locked!" so that the user knows it has been submitted successfully. The only way to confirm it has been successful (at least to my knowledge) is by clicking "I affirm this statement" again and receiving the error prompt "Invalid Entry: Please select a new lock date, or click [Cancel] if you do not wish to change the schedule lock."
