/*  Explanation of URL Variables and their Use !!Important!!  ------------------
    Page will NOT WORK if these guidelines are not followed!

    Below you will find a list of URL variable that can be used
    to control the contact page.

    mode :  controls what is to be displayed on the page
	    
	Values:  email ( shows email form )
		 directory (shows directory spreadsheet)
		 emailSent ( used ONLY by the asp script to show that email was sent)

    reason: controls what option or "reason for contact" is selected in the dropdown
	    and who the email and CC are sent to....very important to get this right!
	    ** Addition values can be added here as needed, as long as the script is updated **
	    
	Values: 
		documentInquiry - used for links for questions on docs
  		graduateInfo - used for links on graduate information
 		undergradInfo - used for links on undergraduate information
  		contactDean	- used for direct email to the dean
  		generalInquiry - used for all links on "Contact Us" or "Request Information"
    
   address: contains the email address of the recipient -- used for direct email links such
	    as those found on the faculty web page.  

	    IMPORTANT!!!!! This property
	    MUST BE USED IN CONJUNCTION with the "fname" and "lname" url variables
	    so that the first and last name of the recipient is displayed 
	
	Values: any pluto email address - will not send email to anyone outside the domain.

   fname:  contains the first name of the email recipient...used in with "address" and "lname"
	   Gets put together with the "lname" and placed in the "reason for contact" list
   
   lname:  contains the last name of the email recipient...used in with "address" and "fname"
	   Gets put together with the "fname" and placed in the "reason for contact" list
