It's clear that I shouldn't be editing when I haven't grasped the basics. By all means revert my edits so it is correct. Perhaps I should leave editing to more experienced people like yourself. I will be visiting several places I have edited next year and it is a pity many places I will be visiting are not very well mapped or are missing many details. I will try and find some some instructional videos before I attempt any more editing. Many thanks for your feedback.

It's clear that I'm not doing things right. Suggest you undo my work if I've messed things up. I will not make any more changes in this area
