In Excel 2000, I'm over looking something and not sure what

When I try to define a type as "Database", "Workspace",
(ex: Dim wrkODBC as Workspace) I keep getting the
error "User undefined type".

When I use any database commands (Connection,Open,Query) I
keep getting "sub or function not defined".

Is there a setting or connection that needs to be made to
make these types and functions available to Excel, or is
it a case not all of the modules being loaded at
installation?
