Why?

I have been wondering ... why can't you deselect a button in an elevator? It is a simple programming task :-) I suppose the big question is what happens when there is only one button selected and the elevator is moving to that floor. Simple, go to that floor unless the user chooses another button then go to the new choice.

Common elevator manufacturers ... this is not rocket science stuff. Have you never got on an elevator with all the buttons pushed by some kid?

TTYL,
