Error Code BCE0019

I can’t find an answer to this error anywhere but my script is for making the character do he run animation when the a or d key is pressed but it says rowNumber isn’t a member of object

#pragma strict

var AT; //Store something

function Start () {
    AT = gameObject.GetComponent(AnimateTexture); //Store AnimateTexture Script
}

function Update () {
    if(Input.GetKey("a")){ //Player moves left
        AT.rowNumber = 1; //Change to running animation
    } else if(Input.GetKey("d")){ //Player moves right
        AT.rowNumber = 1; //Change to running animation
    } else r{ //Player is not moving
        AT.rowNumber = 0; //Change to idle animation!
    }
    
}

And this is why UnityScript is a rubbish language for beginners… you haven’t typed your variables.

var AT;

should be:

var AT : AnimateTexture;
