Eye tracking rig won't work

Support Animation and Rigging

I’m trying to make a 2d texture track and bone to steer the eyes. I’m using a driver to track to the bone. The driver seems to not work like it did in many of my other rigs. I’m leaving a link to the model to see exactly what i’m talking about. https://drive.google.com/file/d/1fP3MFB2JWN4Y2g4pbjQp-2G7qI-hFouu/view?usp=sharing

Turn your snapping off. I don’t see the issue?

Well the issue is when you move the eyes_ik bone the eyes should be tracking its location using a driver placed on the image texture.

Turn your snapping off.

Hi, Your eye’s mesh are made of three layers only one eye back layer has a driver set.
I have moved them apart so you can see.
