Your link helped me figure out my problem, thanks !!!!
I uploaded it on the server of my website and it worked fine
due to the fact that I configured the permissions properly but
unfortunately, I uploaded the guestbook.swf on my customer's
server (I redid their site so they already had their own server set up)
and it doesn't allow me to modify the permissions so I am still one step
away from it finally working on my customer's site.
Besides right clicking on the files themselves and changing all the
permissions on each, is there a way of changing the overall permissions
on a server
( this website and its members really help - thanks guys !!!!)
