Trying to make a standalone signal system...

The flashing works perfect now. Thanx.
The only thing left is the code buttons.
Here is the current code

void updateRouteNumber() {

  for (byte n = 0; n < numCodeButtons; n ++) {
    if (route == 0) {
      if (digitalRead(codeButtonPin[0]) == HIGH) {
        route = 10;
        Serial.println("Route = 10");
        delay(50);
      }
      else if (digitalRead(codeButtonPin[1]) == HIGH) {
        route = 20;
        Serial.println("Route = 20");
        delay(50);
      }
      else if (digitalRead(codeButtonPin[2]) == HIGH) {
        route = 30;
        Serial.println("Route = 30");
        delay(50);
      }
      else if (digitalRead(codeButtonPin[3]) == HIGH) {
        route = 40;
        Serial.println("Route = 40");
        delay(50);
      }
      else if (digitalRead(codeButtonPin[4]) == HIGH) {
        route = 50;
        Serial.println("Route = 50");
        delay(50);
      }
      else if (digitalRead(codeButtonPin[5]) == HIGH) {
        route = 60;
        Serial.println("Route = 60");
        delay(50);
      }
    }
    if (route > 9) {
      if (digitalRead(codeButtonPin[0]) == HIGH) {
        route + 1;
        Serial.println("Route + 1");
      }
      else if (digitalRead(codeButtonPin[1]) == HIGH) {
        route + 2;
        Serial.println("Route + 2");
      }
      else if (digitalRead(codeButtonPin[2]) == HIGH) {
        route + 3;
        Serial.println("Route + 3");
      }
      else if (digitalRead(codeButtonPin[3]) == HIGH) {
        route + 4;
        Serial.println("Route + 4");
      }
      else if (digitalRead(codeButtonPin[4]) == HIGH) {
        route + 5;
        Serial.println("Route + 5");
      }
      else if (digitalRead(codeButtonPin[5]) == HIGH) {
        route + 6;
        Serial.println("Route + 6");
      }
    }
  }
}

then if route = 14 itll do one thing.
and so on...
I just need to get to that number. Right now if route =0 and i press button 1 the serial display shows
route=10;
route +1;
and it wont process the second push.

Thanx
