I suggest drawing a really big box, labeled "ALU" with all the input and output wires.

Then inside that box, start drawing your internal parts and connecting those wires to each other.

The first problem I see is that you got an output wire, "out", connected to an input wire "Or16Way(in=out...", "Or16(...b=out..."

You can't do that.

Then you have a wire, "drop", that's not connected to anything at all.
