Still no help
Hmmm. Not here at you're beck & call - be polite!
You say you are new, have you managed to get other sketches working?
I don't know this stepper card.
If you connect dir & step to LED's to they light (I assume you have no scope, or maybe a multimeter?) - i.e. are you producing signals?
Since there is no clock, can you static drive the card by manually supplying signals to these two pins.
It was said above that you may have a dud board, so you need to isolate where the problem is - Arduino pins, software, the board, the motor, power-supply.
Where does your 12V come from? does it provide enough current?
