Skiing - Launching off a slope? I'm sticking to the gound!

Ahh… now I see… I had since found all the separate nodes that I had to chain together to get the same setup, but doing it this way is much cleaner. One more question and then I’ll stop bothering you. At the end you do some math for 100-CurrentSpeed and I see your CurrentSpeed variable over on the left, but it isn’t set here. What do I need to do to get that?
