I told you in your last post that you cannot "superhide" a column and provided code to hide a column and protect the sheet which is all you can do, so why waste members' time?
royUK Yes I know that, and you told me so. I only wanted (and maybe I didnt use the correct meaning and title) to understand why the code I posted not working. It gives me an error. I apologies to all members , I really dont want to waste time! I only want to lock the column from editing. This thread of course can be locked if it is against forum rules. Sorry
