Here are some notes on IndexOutOfRangeException and ArgumentOutOfRangeException:

http://plbm.com/?p=236

Steps to success:
- find which collection it is (critical first step!)
- find out why it has fewer items than you expect
- fix whatever logic is making the indexing value exceed the collection
- remember you might have more than one instance of this script in your scene/prefab
