[kioshi]

1) Script Title: Conveyor Belt slideshow script

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex14/leftrightslide.htm

3) Describe problem: I've just discovered this script and i'm lost/new to java, scripts, everything! i placed it on my site and try and run it with images i've put into the code, but it doesnt show up anywhere, all my other flash files work but this....it just doesnt seem to want to show up. can someone look over this code and assist me, am i just looking over something very beginner like?

heres a copy of the script and what i've done to it. i saw some other threads and read them with little understanding. thanks in advance.
i hope this isn't a problem with any admin on this site.

Unless you've edited after:


////NO NEED TO EDIT BELOW THIS LINE////////////

what you show looks fine. But unless you have the three dynamicbook images, having them missing will certainly at least mess up the look of things in some browsers and you may be using too few images to get anything really happening. There could always be a problem other than any indicated by your code, so:

Please post a link to the page on your site that contains the problematic code so we can check it out.

the site is still under construction and has yet to be published online. i'm working on it from my computer and previewing it in multiple browsers [IE,FF] and Opera]

Well if you want more help, zip up a demo with all the images and attach it to a message, or put a live demo (preferred) up on the web somewhere that I can see it.
