Anton,
Thanks so much for your reply. I got it working on my own, but I really appreciate it. Could you tell me what you mean by two scenes?
and could you tell me what you mean by a "temporary" box?
I'll reupload my model on this thread as soon as I finish the other folding leg. My end plan is to use a modified trailer jack to power the scissors up and down. The trailer jack will be driven by a parts of a broken cordless drill.
