	Several forms all use the same block of common elements for input
	so this code will check all of those in a standard way to
	avoid duplication.
	
	Note that this supports the use of non-machine-readable security graphic.

	The common items are (* means compulsory):
	
		Name *
		Job Title
		Company
		Email *
		Email Confirm *
		Phone
		Security Code (Captcha) *
		
		
		checkAddress is passed in from the calling function, having been
		set from the PHP $checkAddress passed via the onSubmit() call.
		
		0 = no Address checking
		1 = check Address but completion is optional
		2 = check Address and it is compulsory
