I have tried to make a flip book slideshow as submitted by Ger Versluis. I keep getting an error message that "Book_Div is null or not an object."

Here is my page: http://marymargaret.home.att.net/sam.htm

At the bottom of your script, (around 10 lines from </html>) , you have this line of code:

<img src="placeholder.gif" width="454" height="302">

Which should read:

<div id="Book" style="position:relative">
<img src="placeholder.gif" width="454" height="302">
</div>

I haven't loaded all my photos yet, but I can see now that it works. It makes me wonder if Front Page Express deleted the lines that I needed. Happy new year!
