problem with SetObjectView

[Neutron]

i want to have an object that plays an animation of smoke, so i make a view with the appropriate frames, then i make an object, give it an image, put it where it needs to go, then i press the 'edit script' button in the settings window, and enter: SetObjectView(0,3); onto line 2, save, and exit.  then, i go to save the room, and it tells me there is an error with SetObjectView, and do i want to fix it.  admittedly, i haven't attempted room scripting, or anything other than making dialogues, but, it seemed pretty straightforward.  Does anyone know where I went astray? I realize i can set the view through the interaction options, or make the smoke part of an animated background, but I am just curious as to where I went wrong with the room editing.

What's the exact error message?

Where did you put the line of script? Did you just edit the room script and just put it outside of a function? (which shouldn't work)
You shall put it into a function, like eg.
in the interaction editor, set the interaction for the event "Player enters screen before fade-in" to "run script", then press "edit script" and put the line there.
