Ask the Experts / MOM not working.

For some reason when I try to make tables the way you guys told me, they glitch to the point where they're pretty much not even there, so I'm trying a new method. I'm trying to build them on an elevated deck, so I made the deck first, and on the ground made the benches and the tables, and I'm trying to raise them up to the deck with MOM. I enter everything in but when I press OK, nothing happens. It worked with only the benches earlier, but when I tried to put the actual tables in the same insane glitch happened, so I deleted them and started again. For some reason this time, it's not working.

Stay-at-home moms are okay, man. Don't knock their efforts!
