OnTriggerEnter Problem Unity 5.1.3f1x

While doing the first tutorial, I found the following problem: onTriggerEnter would not recognize a game.object entering a trigger. The pickups have this exact tag, are triggers, and have Rigidbodies(to allow them to become dynamic objects). The sphere has a Rigidbody and Sphere Collider, and the script is attached to the sphere. I tried reinstalling Unity, but it did not help.
My code: (This is C#)

void onTriggerEnter(Collider other)
{ Debug.Log (“Triggered c”);

if (other.gameObject.CompareTag (“Pick up”))
{ other.gameObject.SetActive (false);

Debug.Log (“Triggered d”); } }

I also put Logs earlier in the script, in void.Start and void.Update, and they work fine. The debugs in this snippet don’t, however. I used the exact same script as in the tutorial, with the exception of various strings, which are irrelevant. Finally, there are no errors in the Console. I searched for other with this problem, but only found one, whose advice did not work in my case.

Is OnTriggerEnter and not onTriggerEnter.

Yes, look at the script.

Problem solved, misunderstood your explanation _7stars.
