How can I assign button/buttons to XL 2007 by Macro for different
 

Hi :
I want to create a project report sheet format, using Macro to change the
names of projects and its addresses in the first rows to be changed when I
click the button.
E.G:
Project A with its address in merged cell A1:F1 changes when I click the
button A, on the cell M3.
Project B with its information changes in the same merged cell A1:F1 when I
click the button B on the cell M4.
And so on.
Is it possible with VBA or there is other way??

I appreciate any help in advance.
