Help to fix zoom on pageflip - desperate :(

Hi guys

I have attached a zipped fla this file which should zoom in and out of a page flip flash file,

However my zoom as you can see goes all wrong! It works but the pages move all over the page, I do also need to add scroll bars but they can come when i fix this ■■■■ zoom!

Could anyone help and take a look before I go mad

I am more than willing to sort you out some $ for time spent.

Thanks for your time.
