This file is dependent on the frmConsolidate.js file. We re-display the strcuture after we sort
Need Object Data
	1. FP Number (server side this is needed to determine the sub dir)
	2. Collection of Items
			chkBoxId 		- to reference the check box per line; this is unique
		 	sOrd				-	the server side Print Order 
		 	subDirName	-	where the files are located on the server 
										(more for development / debug cycles)
		 	fileName		-	the name of the PDF file tol consolidate
		 	innerHTML		- the contents between  the TR table elements
