Hello Everyone!

I have a bit of a situation and I'm hoping you guys/gals can help me out. I attached a sheet so you can see what I'm working with. If you look at column A in sheet labeled "Order" you see a list of SKU's. Then on Sheet labeled "Overstock" you see another list of SKU's. I'm trying to see if any of the SKU's in Overstock column A match up with the Order Column A. Is there a formula that would help me figure this out? Hopefully that makes sense. Thank you for any help you can give!OS Warehouse.xlsx
