Just passing by, make sure you aren't zoomed in or panned away from the axis when you look. Check to see if there is some way you could be referencing a matrix. I can pull up a similar error by trying to pull a value out of a non-existant slot. I got my first TI 2 days ago, so I probably don't know as much as you.
