Use a pull-down resistor instead of leaving a node disconnected.

Or see "Inverter" in examples.

Okay, see what I added. It didn't help much.

I have published a new circuit illustrating a pull-down resistor.

Did i fix it? The AND gate acts right, but the OR acts like an AND and the XORis hosed.

Pull-down resistors need to be at all inputs of all logic gates. See the circuit I just published.

Okay. Works now.
