LevelStatus in the 3D Platformer tutorial refuses to work(Using Unity 3.5).

I've been following the 3D Platform tutorial for quite some time now, already aware of how outdated it is for Unity's current version. Now, I'm trying to make Unity work so that the Impound Fence object disappears like it's supposed to after I collect a required amount of cans. Unfortunately, when I do collect them, the camera causes the game to pause(which I respond by unpausing the game) and does nothing about fence. Nothing happens with other parts of Level Status script either, such as improperly-working cutscenes and nothing happening when I touch the ship to end the game.
