Trying to Learn: Preventing Distortion with the Puppet Pin and Starch Pin tool

Supposedly this will teach me to Apply Expressions to the Sliders that I addded to the Null Objects to prevent too much distortion to the Puppet Pins. (Link)

What'd I just say?

Update: This lesson used the Puppet Pins and Starch Pins to prevent too much distortion when you use the Null objects to distort the face.

Red Dots are the Starch pins, the Yellow X are the Puppet pins.  The yellow X with a red "null" box attached to them are the animatable distortion areas of the face.
