Why am I being told 'quack' is not a generic definition?

Assets/Scripts/HandGunDamage.js(6,27): BCE0138: ‘quack’ is not a generic definition.
var DamageAmount : int = 34;
var TargetDistance : float;
var AllowedRange : float = 75;

function Update()
{if (!GetComponent.parent.<Animation>().isPlaying) {
{if(Input.GetButtonDown("Attack"))
	{var Shot : RaycastHit;
		if (Physics.Raycast (transform.position, transform.TransformDirection(Vector3.forward), Shot))
			{TargetDistance = Shot.distance;
		if (TargetDistance < AllowedRange)
{Shot.transform.SendMessage("DeductPoints", DamageAmount);}}}}}}

I don’t use Javascript, but this line (which I think is line 6, but hard to tell) looks wrong:

if (!GetComponent.parent.<Animation>().isPlaying)

What are you trying to do here? Find out whether the animation component on the parent object of this transform is not playing? Then that would probably be:

if (!transform.parent.GetComponent.<Animation>().isPlaying)
