Slender pages

I am using Alucard's slender guide to make a game similar to it. I am using the spherecast script he provides in a video, because the link to his scripts just crashes if I open it in Internet explorer on any computer I use. Using the script there are no errors but pressing E or clicking does not pick up a page. I try from every angle, very close up and a bit far back, I even messed with the distance and changed it to 2, 2.5, 5, 5.5. I do not understand what is wrong. It'd help if someone used the script in their Unity and tried to figure out what's wrong.
Here it is:

Code (CSharp):

1. #pragma strict
2. var papers : int = 0;
3. var papersToWin : int = 4;
4. var distanceToPaper : float = 5.5;
5. var sphereRadius : float = 1.0;
6. function Update()
7. {
8. if ( Input.GetMouseButtonDown(0) || Input.GetKeyDown( KeyCode.E ) )
9. {
10. var hit: RaycastHit;
11. var rayOrigin : Ray = Camera.main.ScreenPointToRay( Vector3( Screen.width * 0.5, Screen.height *0.5, 0 ) );
12. if ( Physics.SphereCast( rayOrigin, sphereRadius, hit, distanceToPaper ) )
13. {
14. Debug.Log( "Test" );
15. if ( hit.collider.gameObject.name == "Paper" )
16. {
17. Debug.Log( "Tests" );
18. papers += 1;
19. Destroy( hit.collider.gameObject );
20. if ( papers == papersToWin )
21. {
22. Debug.Log( "You have collected all of the Papers !" );
23. }
24. }
25. }
26. }
27. }

EDIT: Also the cubes are named Paper, forgot to mention that.
