You don't have an inheritance problem. You have a static problem.

You either need to make "d" static, or remove "static" from "tabe".

And while in this case, it's easy enough to see the problem in your
code, you really should get in the habit of providing more detailed
information.

It's good that you posted the complete error text, but you should also
indicate exactly where in your code is the line and column that the
error occurs (and note that the exact numbers aren't useful to us…you
need to look at the numbers, and then identify that location in the code
some other way).
