/*
This script sets the targets for an email containing the information on the page to the user's department (based on the 
drop-down list), the bursar (if there is an address change), and the user (for verification).  It finds these three 
targets in the first three methods, then combines them into a single string, and finally sets this string as the value 
for the '*recipient' element, which is used by a university script to send an email.
NOTE: The script also contains an unrelated method that sets the radio button list appropriately if the user changes the 
'different from above' textfield.
