A. - This is the wrong place for help on scripts (web apps & programs). This is a forum for help with installation and support for XAMPP.
B. - Joomla has its own online docs/wiki and support forum. The people there are expertshttp://docs.joomla.org/http://forum.joomla.org/
If you run into trouble with the XAMPP side of things we will still be here
Good Luck with your project.
