Thanks for your reply. You can download the module and have a look for and hopefully shed some light on how it can be done :)
If you lazy like me, I've included the code for you below  8) 
Yeah I paid for this contribution, mainly because I find it very good for my current store and it drives sales. I was disappointed when the module was never updated for MS1 and MS2 and when I asked on the board no-one seem to feel the same as i did about this mod. So I guessing paying was the only was to it.
