When i try to run it to something to core a point this error comes up:MissingFieldException: Field'System.Object.tag' not found.

My Script:(attached to 'point')

var score = 0;

print("Score: "+score);

function OnTriggerEnter( hit : Collider ) {

if(Object.tag == "player")
{
    score += 5;
Destroy(gameObject);  

}

}

And I checked, my player is tagged with the all lower case word, "player"!
