were you able to make it work? after uploading your code it just counts till 9, and it dosen't shiftout to next digit rather both digits show same numbers

ok, let’s get back to basics...
we have your code, now post a complete wiring diagram (schematic) of how all your parts are connected together.
Not fritzing, a real pen on paper, or cad drawing that shows all the connections and parts.
It’s already been said this is a hardware problem, so we need to see how you’ve plonked the bits together. You can keep burning boards as long as you want, but to help, we need to see what’s happening.
This thread started about a year ago. I suspect th OP has moved on by now and the thread has been high jacked.
oops - thanks!

Hi,
Welcome to the forum.
You will be better to start a new thread.
