non acces static member error

#pragma strict

static var specialeffecton : int = 1;
static var speedeffectsize  :float = 0.3;
 var bluuur : float;

function Start () {
}

function Update () {
bluuur = Mathf.Lerp(1,0.2,Car_Movement.currentspeed/Car_Movement.topspeed);
Bloom.bloomThreshhold = bluuur;}

And he’s my error

Assets/Standard Assets/Scripts/My Scripts/sets.js(13,7): BCE0020: An instance of type ‘Bloom’ is required to access non static member ‘bloomThreshhold’.

I totally i don’t know what i have wrong.

PS : Bloom is standard pro asset.

You need to reference an instance of Bloom, either by using the GetComponent method, or by setting a public variable, like this:

public var bloomInstance : Bloom;

Then change line 12 to:

bloomInstance.bloomThreshhold = bluuur;}
