TM1803 radioshack "Tricolor LED strip"


i purchased "tricolor led strip" @ local radioshack. have been troubleshooting problem days now, , need assistance, due beginning skills arduino. using pololu color tester code:
code: [select]

#include <pololuledstrip.h>

// create ledstrip object on pin 12.
pololuledstrip<12> ledstrip;

// create buffer holding 60 colors.  takes 180 bytes.
#define led_count 60
rgb_color colors[led_count];

void setup()
{
  // start serial port, communication pc.
  serial.begin(115200);
  serial.println("ready receive colors.");
}

void loop()
{
  // if digit received, go integer parsing mode
  // until 3 calls parseint return interger or time out.
  if (serial.available())
  {
    char c = serial.peek();
    if (!(c >= '0' && c <= '9'))
    {
      serial.read(); // discard non-digit character
    }
    else
    {
      // read color computer.
      rgb_color color;
      color.red = serial.parseint();
      color.green = serial.parseint();
      color.blue = serial.parseint();

      // update colors buffer.
      for(byte = 0; < led_count; i++)
      {
        colors[i] = color;
      }

      // write led strip.
      ledstrip.write(colors, led_count); 

      serial.print("showing color: ");
      serial.print(color.red);
      serial.print(",");
      serial.print(color.green);
      serial.print(",");
      serial.println(color.blue);
    }
  }
}

on arduino uno. problem strip displaying green second 3 leds on strip. have + distributed strip , vin, have - distributed gnd , strip, , have data in pin 12. please can't afford spend day googling away @ computer solution.
