Now, to answer e4xit:
Could you show me the lines from the blockchain (not the website) which show the 'balance' for this address you have selected as I can't find them and I have been searching for hours, thanks.

The balance is calculated from the inputs and outputs to that address. You would need to know how to do arithmetic to figure it out (or have your computer or friend do it for you).
I thought you might answer something like "do arithmetic"... I hate to say it but I think that I must agree with some of the other members who have posted here when they say that I think you lack quite a lot of understanding regarding bitcoin: the protocol.
NB. I'm not saying that I think that you don't understand bitcoin: the idea.
