Hi, I'm an Italian newbie of SP.
I'm using a short guide to learn about this program, but I've encountered an error when I tried to put a controller name in a hinge.
The error is:
Formula doesn't compile:
"name I put in the box"
(eval):1:in "getBinding": undefined local variable or method 'name I put' for #MSketchyPhysis3::ControllerContext:0x9d434f8

I tried with different type of group, hinge condition but the problem still remain.

And... There is a manual, in with is explained every feature and option of SP?

This is the first time I used a forum , and my english is very little... So please be clear.
