Pages Not Turning/flipping
I've got a flipper page book (from http://www.iparigrafika.hu/pageflip). It all works fine, but when I add my own pages and follow the instructions for doing so it doesn't work proberly. If I roll over the right top corner then bottom left corner turns up as well and vice versa. (I've uploaded the file to: http://www.lucyohara.talktalk.net/pageflip.swf) I've looked at the code, but don't really understand which bit would control it. I've attached the code that was in the file.
Thanks
Code:
