Rotate secret book shelf with moveable book

[Efendi]

Hello. I have a problem when i want to rotate the secret book shelf using a moveable book. The problem is that the shelf is not moving at all.

Here is the script:

Spoiler below!

void OnStart();

{

AddEntityCollideCallback("Book", "Book_Area", "func_shelf", true, 1);

}

void func_shelf(string &in asEntity, int alState)

{
if (alState == 1)
{
SetMoveObjectState("Shelf", 1);

}

}

I have named the moveable book to "Book", and placed a area near the book, and i have named it "Book_Area". The shelf name is "Shelf", and i have places a area near the corner of the shelf, where i want it to rotate, and named it "RotateShelf, and i have named the "RotateShelf" in the AngularOffsetArea on the Shelf.

Any help would be highly appreciated! Thanks in advance!
