The match() routine returns nil when there are no results found.  You
will want to check for this case before passing the results to another
function.

You should rewrite it like this:

    results = match(admin, 'INBOX', nagios)

    if (results ~= nil)
    then
	move(admin, 'INBOX', admin, 'nagios', results)
    end
