function inaircollsends(){
GameObject.FindWithTag("skatergrind1").collider2D.isTrigger=true;
}

GameObject.FindWithTag("skatergrind1").collider2D.isTrigger=false;
}

function inaircollsends(){
GameObjects.FindWithTag(“skatergrind1”).collider2D.isTrigger=true;
}
function inaircolls(){
GameObjects.FindWithTag(“skatergrind1”).collider2D.isTrigger=false;
}
you need to add S to Object because you want to video more than one object you search for objects :smiley:
