Animating on Trigger

I have a block that I want to animate when the player touches it. I've made a slightly bigger box collider around the one that give it a physical property and have set that to a trigger. Here's my code

function OnTriggerEnter2D(Other : Collider2D){
if(Other.gameObject.tag == "Player"){
audio.Play();
animation.Play(); }
else {
audio.Stop(); } }

The audio is playing perfectly so the if statement is working. Can any one tell me what's wrong with my code?
