Boolean values not behaving as expected. Please Help?!

I have a mouseOver script (see below) that I'm using in a project that is used with the Kinect controller. So you actually "click" or "select" things by hovering over them for a long enough time.

The last if statement is where I noticed this problem. I'm trying to prevent the "zoomIn" and "zoomOut" button detection while any of these three booleans are true:

 zoomedIn, movingUp, movingDown

The Problem: The print() at the 2nd to last line of the below code ALWAYS returns false. But I know that's not true, because if I comment out any of the places where those booleans are set to "true", the iTweens don't happen or it skips other functionality that I would expect. So it seems there's something about checking them on Update() or that somehow the booleans are getting reset. I know for a fact that these booleans do not exist in any other scripts in the scene.

It should be noted that this script is attached to a prefab that is instantiated several times procedurally via another script. (You can mouseOver any of them and that object is animated, zoomed in on, etc.

I have spent hours and hours on this, and I'm stumped. I feel like it must be something obvious.
