the '#' operator works only for 'arrays' that is, tables indexed by numbers
from 1 to n, without holes.
there's not a general 'table size' operator in Lua

from the manual:
"The syntax var.Name is just syntactic sugar for var["Name"]"
note that 'Name' isn't any kind of string; also from the manual:
"Names (also called identifiers) in Lua can be any string of letters, digits,
and underscores, not beginning with a digit. This coincides with the
definition of names in most languages."
so, your table's keys are not 'Names', since they begin with a digit
