VLookUp formula not working

Hello All,

One of the formulas I use frequently is not working on my excel sheet. I work with ad campaigns and the formula I use to match ad placement Id's to the ad placement nicknames we give them is now working. Can anyone help me?

Here is the formula and some screenshots:
=VLOOKUP([@[Placement ID]],Table3,2,FALSE)

This screenshot is from my first table:

This is from my second table (however when i select this table the formula lists it as table3):
