Help with door animation

Ok this is p robably around somewhere but i need it quickly

I have a sctructure with an "Entrance door" [preanimated in cinema 4d]

In cinema 4d this door is animated as follows:

door opens: frames 0 - 25

door closes: 30 - 55

closed position: 55 - 60 [the door does animated correctly in cinema 4d etc]

In Unity

Entrance door > Inspector panel > animation (is ticked) >Animation (none)

I also have the following script titled 'animationTrigger'

//the trigger function OnTriggerEnter (col : Collider) { var door : GameObject = GameObject.Find("entrance door"); door.animation.Play("open"); }

function OnTriggerExit (col : Collider) { var door : GameObject = GameObject.Find("entrance door"); door.animation.Play("close"); }

however

I also have a cube which is a trigger (it is ticked).

What else do i need to do to make the door open and close whenn my fps walks up to it??

Please explain simply im not an expert. Sorry and thanks!
