Please help me by checking if my program is correct or giving the correct ladder program. I keep getting "Invalid input. - input required but omitted" this error for all the variables in first rung. I'm a newbie to ladder programming and done this much on what I understood by reading different sites on begginer ladder programs.
It would be also helpful if anyone could suggest me any source for learning the ladder programming (ones with many programs with both the problem statement & ladder program for each question).
