Harvey, I slept good. it's so clear now. The jumper had to be shipped plugged in so you could move the base down to attach the platform. Then the platform had to be plugged in, because of the limit safety switches in the base pan, and the the jumper unplugged. Was the unplugged base the reason for the upper door not unlocking?
Now if you can just figure out how to make the thumbnails click large, you will be good to go!
We all worked together well, that always make the job not a job but a get-together. I't was really good to see Jim improve in his mobility and communications from the beginning of the week to the end of the week. He is a fighter.
