Digital Clock Circuit's & Diagrams?

I am using Multisim to build a digital clock circuit and I already have the circuit set up, the only thing is I’m having a few difficulties with the digits for the hours, the last digit which should only be a one or zero is starting at a random number, and different every time I start the circuit, I know an AND gate is needed somewhere but don't know where exactly I can e-mail a screen shot of the circuit to anyone that can help. Also if anyone knows how I can set the time or what chip I can use to set the time will be greatly appreciated. Thank You
