Lua HELP (idk lua)

here you go! you mustn't delete the function step and init!
the upper one is for variables and stuff which should just happen for one frame.
the lower one is done EVERY FRAME so it CHECKS EVERYTIME IF IT RECEIVES A SIGNAL and as long as it does it sends one out too.

Don't know why but you have to use bigger sign and equal together or it will give you an error
