If you look closely at the picture, you will notice you can see the raised copper line under the black coating. Following that line you can see the circuit is set up as 24 in series.
As for why it does't work? There could be a number of things wrong and without knowing the whole setup i couldn't say for definite but with the information given and looking at the circuit i would say he isn't putting the correct voltage across. Biggest mistake anyone trying to DIY something who don't know anything about series or parallel circuits is to use the wrong voltage on a series circuit. They think that say an led has 2.4 volts that you put across it that that same 2.4 volts would go over all of them, but if it's 24 in series you would need 2.4x24, which would be 57.6 volts. LED's also have a minimum voltage requirement to work which in this could be for example 2v. So to even turn these LED's on and see something you would need 2x24, which is 48volts. This is assuming all the leds are the same, if there are ones which need higher voltage but lower current then you could be in some serious difficulty.
