I’ve put all three sections of pole together pulling cord through. I then tried to attach the 4 assembled poles to the bas. The base is very heavy and the male end (I think)doesn’t screw into the receptacle and doesn’t go through the “pretty “ top of the base to the underside where it is supposed to be tightened by a nut . I don’t know what to do, I really like the lamp but if I can’t get it all the way securely together I’ll have to return it and I really don’t want to do that. Can you help me please to conquer this step in the process. Thanks. Eileen
