Adding a new region to Framework

Hi, can anyone help me. I must be missing something really obvious here.

I want to add another region to Framework so that I can add a big picture banner under the navigation bar.

To do this I have followed the very helpful posts about how to do this but my new region just doesn't show up.

Here is what I have done so far:

I added the new region to the .info file like so

regions[left] = Left sidebar
regions[right] = Right sidebar
regions[content] = Content
regions[header] = Header
regions[footer] = Footer
regions[jesbanner] = Banner

Then I added the following php to the page.tpl.php file

if ($jesbanner):

endif;

I added some css to the style.php

#jes-banner {
margin: 0;
padding: 0;
height:200px;
background-color: #333333;
}

Lastly I emptied the cache as instructed

1. site configuration / performance and clear cache.
2. going to site building / themes and re-enabling my framework theme

The region doesn't show up in the list when I go to enable blocks so its obvoiusly not recognising the change to the .info file

Hope you can help

Thanks
