Nothing wrong, you need to go to toolsadd-ins, select ATP (Analysis
ToolPak,)
if it was installed when office /excel was installed it will be available,
if not you would need the Excel/Office CD and follow the instructions to
install it.

I tried on MS Excecl 2007 and it worked just fine. I wonder what can
be wrong in MS Excel 2003.

Any ideas???
