OnTriggerEnter is giving me nothing

I have a script set up that should be straightforward and tell me when an item passes through a box collider. First off I’ll include the script:

using UnityEngine;
using System.Collections;

public class Fecal : MonoBehaviour

    void onTriggerEnter (Collider other)
        print(gameObject.name + " was triggered by " + other.gameObject.name);
//                PoopTracker.UpdatePoop(1);


(this is a clean up behind your dog sim…)

I’ve been reading documention & going through old answers for 4 hours trying to figure this out and I’ve got nothing so far. I have a simple cube that sits flat with a box collider above it (and all around it to be safe) that is a placeholder for a trashcan that I need to know if another object passes through. It is a rigid body, with a trigger, no gravity, no kinematic. I’ve tried it with each of these options reversed as well.

The other objects are simple cubes representing the crap. They are also rigid body but without triggers and also they have no kinematic applied. A box collider is applied to these items as well (I’ve tried other shapes colliders multiple times as well just to rule out any possibility).

I’m getting nothing in the console telling me that there is anything happening.

I’ve been coding for about a week so I’d really like to apologize for not being able to find there answer to this easy question myself, but I just need direction now. I’m comfortable with reading documentation if I can be told which documentation I should be in.

Try OnTriggerEnter with a capital O.
