Is this possible? Because when I try to remove the Value number of the map I wan't to remove I get an error message.. Can anyone explain how to do this correctly?

Thanks In Advance

just remove everything except the value, when your on the menu it will have the slot for the map but no name will be there, im not sure how to remove it all the way.
