Error 296

[Glyn]

Been trying to add a storage node to the fog system & am getting the following error:
Setting up fog userinstallfog.sh: 296: Bad substitution
I already have a storage node, but this has filled up so I need to add a new one.
I get this error after the setup & installation of the packages.
I would like to get this sorted as soon as possible as I have images to create.
I am using Ubuntu 11.10 for all Fog systems.
Cheers

Answered this one myself.
Install Ubuntu 10.04 & it installed with no problems.
