Dreamweaver CS4 close button snippet

I am new to the close window snippet and was wondering if anyone could tell me why my window isn’t closing? It is the snippet from CS4, the close window button is showing up. It just isn’t closing the window. Any thoughts?

<input name=“Button” type=“button” onClick=“javascript:self.close(); onKeyPress=” value=“Close Window"javascript:self.close();”><br>
