rigid body problem

when my animated character hit a box the box staring to move forward

my need is when my character hit a box collision should happen and message should display

when my character hit the box the message is displaying but the box is dragging along with the character

otherwise it will move side ways.I have applied both rigid body,angular drag and drag but not working

Your character should have a Collider and a Rigidbody, the box a BoxCollider only.
