Space in the price

How do I get rid of the space in the price?

I have '£1 200' rather than '£1200'.
'£1,200' would be fine - anything but the space.

Thanks very much.

You need to go in the menu System->Currencies and edit your currency. There, on the right of the screen, you have all the necessary options for that.
You could put a , in the field "Groups separation" or remove the space.
