Only 4 LEDs light up? Answered

I have soldered the wires for the 19 LEDs and I only get 4 LEDs to light and change color. The code has been downloaded to the Arduino. I cut another 19 LEDs strip, soldered the wires, and still only 4 LEDs light up. I have the three wires on the Arduino and nothing else is connected. Any ideas?
