Uno + 4 Wire Stepper Motor + 15V Power Supply Setup

Hey guys, I have a question on how to wire my NEMA 17 Stepper Motor with an EasyDriver to an Arduino Uno. I have it up before and it has worked properly, but this time I have added a barrel jack to apply 15V from an AC to DC converter. Right now I can't seem to figure out what is wrong. Here is a picture of the setup:
What connection do I have wrong?

Ok I think I found the problem. So I replaced my driver with a new one and had to solder male header pins. If you look closely at the step and dir pins, they are soldered together haha
