Collider Activate Trigger Animation

So I've been trying to set up an automated door with animation that'll triggered by a collider with activate trigger, but it doesn't work. each time i entered the collider the trigger count keep add in negative value.

The activate trigger target i set it to the object that have animation but i put it under an empty gameobject.

Can someone help me figure out whats wrong?

will this has anything to do with the animator controller that i make a new empty state and set it to default to prevent the animation start when i hit play?
