Welcome to Changoo.org, Glad you are here, first of all i would like to inform you that before post a question please read the forum instruction from the given link
Your post says nothing about your problem “help” as a title gives know idea of your problem, “Help”is why this board is here, if you give a descriptive tile then you stand more chance of getting the right help. Members have different skills in Excel and may only visit certain sections of the forum, titles that just say “help” may not attract the right help. Members have busy lives to live, they have jobs to go to, families to take care of and a life outside of Chandoo world and do not spend all their time trawling through the posts.
If you take a moment to think of the problem your title would convey the help needed and the question you ask will contain more information for the members.

And if you ask why, the answer is: Redmond guys are so special...
