comparator wont read commandblock output

cmdblock 1 can not be read by c1 therefore 2&3&4 can not operate

5 is part of the clock
i guess the comparator cant read the cmdblock fast enough or cant output fast enough as this works with a slower clock than a fill/setblock clock i used in the pic

i need to use the fast clock to achieve what i want to, as the thing i want to detect happens really fast and the game i intend to build may be cheated on or broken if this does not happen fast enough
