Another script problem... Where´s the failure??

Hey guys, i wrote a script for entering a helicopter with an animation. the heli in the world (not functionable) is named "model" and the working one is called "work". when i save the script, a lot of bugreports arrive (missing semicolons, unknown "function OnTriggerEnter" and so on). I have NO idea what the problems are and would be extremly happy if someone could help me / or even writes an example. If it works, i´ll put it in the asset store (of course for free) another question: after i enter the heli, how can i parent the PlayerObject? Regards, me

the code:

 var model = Transform;  
 
 var work = Transform;
 
 function Start () {  
 
 model = true;
 work = false;  
 
 }
 
 function Update () {
 
 function OnTriggerEnter (other : Collider)   {  
 
 model = false;
 work = true;
 function GetComponent(Animation)("Enter");  
 
 }  
 }  

PS: the animation also doesnt work...
