Script to spawn items in random locations not working

Might be because it was wrote for Unity4, but the script doesn't want to work.

Code (JavaScript):

1. //Can be renamed to something else, but its a good example!
2.  
3. var objectType1: GameObject;
4.  
5. var objectType2: GameObject;
6.  
7.  
8.  
9. //Is the number of items to be spawned that is type 1 or type 2
10.  
11. var numberOfType1: int = 5;
12.  
13. var numberOfType2: int = 5;
14.  
15.  
16.  
17. //For checking purposes  to give a count of the number of spawn locations
18.  
19. private var type1SpawnCounter: int;
20.  
21. private var type2SpawnCounter: int;
22.  
23.  
24.  
25. //Will store all the possible spawn points for this item type.
26.  
27. private var type1SpawnPoints:GameObject[];
28.  
29. private var type1SpawnPoints:GameObject[];
30.  
31.  
32.  
33. //Checks to make sure all type 1 items all spawned
34.  
35. private var type1Spawned: int;
36.  
37. private var type2Spawned: int;
38.  
39.  
40.  
41. //Private check to make sure there aren't more items than spawn locations.
42.  
43. private var spawnType1: boolean;
44.  
45. private var spawnType2: boolean;
46.  
47.  
48.  
49.  
50.  
51. function Start()
52.  
53. {
54.

56.

66.

72.  
73.     {
74.

76.  
77.     }
78.  
79.  
80.  
81.      for (var y in type2SpawnPoints)
82.  
83.     {
84.  
85.        type2SpawnCounter++; //Count all spawn points tagged SpawnPoint_Type2
86.  
87.     }
88.  
89.  
90.  
91.     //Error checks
92.  
93.     if(numberOfType1 <= type1SpawnCounter)
94.

180.

184.

212.

214.  
215. }

Error code is "The name 'Item' does not denote a valid type ('not found')."
So, I went looking to see what "Item" is for Unity5. Either I'm bad at searching or it's just not there.
