Want to set Week End Inventory #s to load in Opening Inventory

So back in college I was a bit better a working with excel, but I am now almost 5 years removed and can't get things perfect....

Anyways, at my bar we do a weekly inventory and I have set up an excel document that runs off of opening and closing inventory, obviously the closing inventory for the previous week would be the opening inventory for the following week. I want to write a macro that basically pulls the closing inventory from the previous week into the correct columns in my blank inventory sheet. I need (T4:T271) to copy to (B4:B271) and (V4:V271) to copy to (C4:C271) but then when I re-save the document as the next weeks inventory, this week would be OB LIQ Inventory 9.29.13.xlsm I need the macro to pull from that newly saved workbook to the blank one OB LIQ Inventory.xlsm.

Any help would be greatly appreciated
