	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', ...)

	<textarea name="description" cols="60" rows="10" 
		onKeyDown="wordCounter(this.form.description,this.form.remWords,5);"
