Please help me design a "Multi-digit counter"

thanks , the output should connect to both load input right ? Actually i know RS flip -flop is a reset button , but why i cannot get RS flip-flop in multisim ? i checked all the 74 series ,but don have ,or RS flip-flop not in 74 series?

hi Wifilee,
I have already asked what type of IC gates do you have, tell me, so I can suggest a circuit to replace the 7414's.????

hi,
Post a circuit diagram showing how you connecting the RS flip flop.
