Rigging and animating a book

Hi i am trying to animate and rig a book and have tried and tried for about three weeks to follow a tutorial from CG cookie and cant get it to work.

I am at the stage to just throw in the towel and think of something else to do instead.
My book is almost complete but when i open and close the book the page 1 is supposed to stay in place until i turn it but it goes all over the place because of a scripted expression in the drivers that i cant get right.


Ill put the blend file up too so you can see what im trying to do

Im really getting frustrated now. Can anyone please please help me.

On your armature, turn your display to octahedral and turn your shapes off and look at the direction your bones are turning. Oops not it using minus sorry.

OK. Looking at the bone page_root, it needs to be parented to thickness and then that will get you close so you can copy the formulas.

Cool rig.

Here is adjustments to get your page turning. You still need to add back your lattice crinkles etc.
