With no idea even what type of bike this is (road, MTB, hybrid, ?) it is hard to guess what kind of shifters it might have (brifters, bar ends, down tube, triggers, grip, thumb) to give advice on what steps you might have missed.

Good close-in pictures of your setup, including closeups of the cable runs, would probably help more than any description could.

Don't get insulted, but you do know how to operate Campy shifter, right?

When you pull on the cables and "downshift" the shifters, do they release some cable? Can you move the derailures by hand?

I can fix it! Call me and hold the bike up to the phone.

Could be several things. I can't tell which without more information.....

I'll bet you didn't run the brifters down to the lowest position before securing the cables. So when you snap the button to release cable the cable just gets loose. Otherwise there's no reason at all for the deraileurs to NOT move. Try pulling sideways on a bare cable to add tension while snapping the brifter button that releases tension. I'll bet you end up with a really saggy cable. Adjust and you should be good.

That is a possibility. BUT, according to my Campy experience you have to have the shifters at the correct resting state in order to be able to thread the cable through. You'd need some accidental shifting happening between cable threading and derailer hook up before you lost all function/movement.
