Hi Guys

I'm having trouble with an email message design - it works fine across all devices except android gmail

The box, for some reason, won't go the full width of the window. I think it is something to do with the background image on the cell, which was done using this: http://backgrounds.cm/

A preview of the message can be found here: http://enews.schoolzine.com.au/em/message/email/view.php?id=1198918&u=13851

I've attached an image of what it should look like, and what it does :(

Any help would be amazing!

Cheers
Beau :)
