I'm really not sure why you are posting all these bit's of code, it looks like you have added some lines to some parts but not to others, you have added rbanner4 to the mysql but nothing to the FORUMDISPLAY
If it's not showing in the AdminCP then without looking I'm not sure and seen that I don't have axx to it there's no point in posting the link
One of the reasons it might not be showing is that you have something that prefixes the tables, like vb3_table name
