Collision is not detecting! Why?

I’ve got two objects “b1” and “t1”
I’ve added rigidbody to both, and on b1 checked the “isKinematic”.
on “t1” I’ve checked “Is Trigger”.
And on b1 I’ve added this code:

function OnCollisionEnter(theCollision : Collision) {

    if( == "t1"){




And it’s just not appear to be detecting… Need help people!

In the Box Collider page it says that if you activate “Is Trigger” the collisions will be ignored.

dont tick is trigger. if you want to use isTrigger then using
function OnTriggerEnter (hit:Collider)
