Cannot display correct page in my own computer =(

[afatmagic]

I find a strange thing for my website.
My website use PHP + flash to make. And when I use localhost to view, it works fine.

But when I upload them to another domain server, I cannot read some of the pages.
And the most strange thing is that,
one of the page is a product list with a comboBox, when I use my computer to see,
the comboBox showed but without any product items
but when I use anither computer to view that page, it work fine!
Can anybody tell me what's wrong with it?
