[Closed] Code runs different inside and outside of a FN?

So I’ve got some pretty basic code here, all its doing is trying to set up a camera at a certain angle, zoomed to fit the scene. (If there’s an easier way, let me know!)

Problem is: It runs differently when its enclosed in a function than when its just run straight out.

I’m using Max 2008 32bit, when run as is, it will set up the view correctly… if i uncomment the function brackets, then it will create a camera zoomed in, but from the plan view angle.

 --	 fn setupview =
 --	 (
 		--get rid of any existing perspective views lol
 		viewport.ResetAllViews()
 		viewport.setlayout #layout_1
 		
 		--create a new camera thats oriented how we want
 		angleCam = Freecamera fov:45 pos:[0,0,0]
 		rotate angleCam (angleaxis 45 [0,0,1])
 		in coordsys local rotate angleCam (angleaxis 45 [1,0,0])
 		viewport.setcamera angleCam
 		
 		--set perspective view to match the camera
 		max vpt persp user
 		
 		--zoom to fit everything on the screen
 		select angleCam
 		max select invert
 		max zoomext sel
 		
 		--build a new camera to match the zoomed perspective view, slightly zoomed in via fov
 		isoCam = Freecamera isSelected:on
 		isoCam.fov = 28
 		isoCam.orthoProjection = false
 		isoCam.Transform = Inverse(viewport.getTM())
 		viewport.setcamera isoCam
 --	 )
 -- setupview()
 

could anyone else see if its acts the same?
