Much thanks, in advance, to anyone who can help me. :)

Using Office 2003, I need a formula where the user enters a month for the
current cycle in cell B2, and all subsequent month cells automatically fill
in.

So say the user enters April in B2, then B8 would automatically fill in as
May, and B14 would fill in as June, and so forth.

I also need it to display the full month name and not abbreviated, such as
JUN.

Any ideas?
