GetComponent' is not a member of 'Object'. what does it mean error line 6

function StopBoosters()
{
if(instanBoostersExist == true)
{
var emitter :ParticleEmitter;
ParticleEmitter = instanBoodters.GetComponent(“ParticleEmitter”);
emitter.emit = false;
Destroy(instanBoodters, 1.5);
instanBoostersExist = false;
}

    else 
    {
        return;
    }

It means that instanBoodters is an object. If it’s meant to be a GameObject you need to declare it as such:

var instanBoodters : GameObject;
