Why the Hell is isActiveAndEnabled not working?

Im trying since hours but no result. The UNITY API is extremely frustrating.
Impossible getting to work…

strong textWhy does this not work? unity says:

Assets/Retro Pixel/Scripts/NewBehaviourScript.js(19,13): BCE0019: ‘isActiveAndEnabled’ is not a member of ‘boolean’.

BUT IN THE API EXAMPLE isActiveAndEnabled is declared it is a BOOL !!!

Do why does unity makes problems.

Can anybody help ? Please

#pragma strict





var triggr:boolean;


function Start () {

}

function Update () {

if (triggr.isActiveAndEnabled)

{
print("text");
}

}

Thanks for the answer
