With this code, I wanted to show an button on the page which fires an publish dialog when clicked. When the page loads, it generates an error, when the button is clicked, another error occurs and the dialog is not shown:

I don't know what is going wrong with this. I don't know if the publish_stream permission is really necessary as I am trying to use the facebook dialog. Can anyone help-me?

As Nava Salvatore (and the debugger console) says, you need to add:

somewhere within the <body> of your code. Additionally, your final <script> block should be before the </body> tag (per convention). You don't need any additional permissions for simply displaying a dialog; publish_stream is not needed.
