You need to get hooked up with the Offical osCommerce Support Community to learn how easy it is to fond the answers you need quickly, and with proven practices to follow confidently (follow the link in my signature below).
VodaHost is primarily a Support Community for Blue Voda, and should not be relied on as an osCommerce resource .... whatever little assistance is provided is occasional at best, and aside from offering
Tutorials, VodaHost makes it clear you should turn to Official sources for curent and detailed information (as detailed in red on the Fantastico installation page).
