hello guys

How do I remove page numbers from a double column document in word.

It's a landscaped styled manuscript with like 400 pages. Each page has 2 columns and page number for each columns.

So how do I remove all the page numbers?

In the header and footer section of my word 2016, under the insert tab, when I click on the 'Remove Page Numbers', it does nothing.

The numbers are still there.

Is there a step by step procedure to remove the numbers from the the entire manuscript?

I'd really appreciate the help
Thanks.
