The problem is that the solution described below does not work:
Or8Way(in=outValue[0..7], out=firstPartOr);
Or8Way(in=outValue[8..15], out=secondPartOr);
Or(a=firstPartOr, b=secondPartOr, out=orOut);
Not(in=orOut, out=zr);

I keep getting a sub-bussing error.

Sub bus of an internal node may not be used.
