i need some help with a counter!!!!

guys i really need your help in order to complete one counter...
i almost have it all done...

i have upload the circuit...

every suggestion or criticism is welcome...
i am new to electronics and i am stuck...
also i am already out of date...

so please hurryyyyy!!!!

thanks a lot......

It's an up/down counter. You apply the clock pulse to the UP or DOWN input, depending upon which way you want to count.

Why do you ask questions that are clearly answered in the device data sheet?

What's the hurry? Should this be in the homework forum?
