Be sure that in the Page Tab URL you point to a file in your server that already exist in your server. If you can't access the page, try to add the whole file name in the Page Tab URL like: http://mydomain. Tld/filename.php.
The Settings where you trying to configure the Tab is just not correct. The easiest way to do this is to install http://apps.facebook.com/iframehost and configure it the way you want!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
