That is a feedback node. It holds a value and returns it the next iteration. It works the same as a shift register. So what Florian did is if you have an invalid number, return the previous number.
Of course this doesn't help because if you have 2 invalid numbers in a row, then the first invalid number is what gets pulled out of the feedback node.
Radio buttons are the correct answer here. And if you want them to look like what you have now, then customize them!
