Answer 1

Vance Sibonga Pedroso If you want your comparison to be true if your variable has any value within a list, you should use the 'or' operator (||).
But your problem seems to require comparison with a range. Why not something like:
if (var >= minimum && var <= maximum) {
commands;
}

Answer 2

Because it's different from 2000 and 2002. Since you're using the 'and' operator (&&), the conditional only gets true if the attribute 'Bornyear' equals 2000, 2002 and 2003 at the same time - that is: never. By the way, watch the typo in the second line.
