	Using JM_copySameAs
	This function is used to copy one set of fields to another set, and is usually used to copy
	a billing address to a shipping address.
	All paired fields must be similarly named for this to work, such as billCity and shipCity.
	Also, it is expected that a checkbox is used to toggle the copy on or off.
	The function allows for a variable number of arguments, 
	but the first three arguments MUST be the name of the check box, the first field prefix,
	and the second field prefix.  
	For example, JM_copySameAs('copybilltoship', 'bill', 'ship', 'FirstName', 'LastName', 'Address', ...)

	Using JM_validateDropdowns
	Usually, this function will be used in conjunction with the MM_validateForm() function 
	that Dreamweaver creates to validate a form.
	In this case, alter the onSubmit statement that is created to look like the following:
		MM_validateForm(args); JM_validateDropdowns(fieldList); return (document.MM_returnValue && document.DD_returnValue);
	The fieldList should be replaced by a list of the dropdowns that need to be validated in alternating field name, display name fashion, 
	such as JM_validateDropdowns('state', 'State', 'country', 'Country', 'birthMonth', "Month of Birth', 'birthDay', 'Day of Birth', 'birthYear', 'Year of Birth');
