I'm trying to add the Facebook like box plugin. But when I try to insert it gives me the following message: Unable to find the HTML code for the widget on the widget site or on the clipboard.

- Select the Widget you wish to create.
- Select the button labelled Other to choose where to add the widget. (This step is not necessary for all the facebook widgets)
- Click the Insert button below to add the widget to your page.

But I have chosen the widget and I cant see the button labelled Other?????
Please help
