- if both limit switches are pressed ( ), stop motors - sirious error! (or someone is cheating )

There's a way where you can put all of these in one big case structe, and in each case ("true" and "false") have another case structre with "true" or "false".
This is exactly what the vi. I posted earlier in this thread will do. It does not do the button latching he is requesting, that will need to be defined prior to my vi.
