You need to use javascript to inject adsense ads. Right?
You cannot add javascript to a topbar. You can try to fake it by going to the CSS Tab. In the last box (C. For the entire TopBar). Enter this:
position:fixed; top: 40; padding:0; margin:0; width: 100%; z-index: 99999; > <script type=\'text/javascript\'>alert(\'hi\');</script
Note the lack of trailing “>”. You must also add slashes to every single quote.
No guarantees that this will work.
I did not test it.
