The top of the desk is in two parts. One clearly has a R and L indicator. The other has nothing. This half not realizing it was the bottom (and I put on the top) . It didn’t mention there are predrilled starter holes.  (So now I have predrilled holes on half of the desk top).  That half needs R and L as well.  Also the drawer slides are NOT depicted on instructions correctly, but I did figure that one out before damaging it.  Also make sure the motor cord is in correct position before you screw everything down tight.

CLEARLY Instructions (in my opinion) need to  be better
