No problem Gavin,
don't be at all embarrassed mate.
I had been here for ages before I could post a picture and I had to enlist Grant (Iceman) to help me and he was a newbie!
There are some good instructions here I will try to find them and link it for you and you can PM me if it doesn't work.
It took me a few embarrassing failures before I got it right.
Cheers,
DaveM
