PLease use the # button toplace [ code] and [ /code] tags around your code.

Can you tell us what the goal of your sketch is?

One tip: read about using array's, that could make your code much smaller - http://www.arduino.cc/en/Reference/Array

// partial code

// partial code, will not compile
const int LedPin[9] = {13,12,11,10,9,6,5,4,3};

void setup()
{
  pinMode(inPin, INPUT);
  for (int i = 0; i< 9; i++) pinMode(LedPin[i], OUTPUT);
}

void loop()
{
...
  if (count == n)
  {
    for (int i = 0; i< 2; i++) digitalWrite(LedPin[i], HIGH);
    for (int i = 2; i< 5; i++) digitalWrite(LedPin[i], LOW);
    for (int i = 5; i< 9; i++) digitalWrite(LedPin[i], HIGH);
  }
...
}

You could even use a 2 dimensional array to hold the values for all the pins for a certain value of count, and then you can do most of your code in one line:

for (int i=0; i<9; i++) digitalWrite(LedPin[i], value[count][i]);

This is totally the wrong section.

Without asking a question it is hard to help.

Your only other previous post talked about a count down clock. However looking at the code, which I have seen several times from different people it looks like you are trying to get us to do your homework for you.
