	Description: This script analyses the form contents and returns false for empty fields 
	and true if all fields are filled out: user is disallowed from sending the form until something 
	is provided 
	The cursor is focussed to the relevant field and an error message is given to the user. 
	
	Further Development: Add elements[n] for extra fields to customise the form validation.
