servo coding issue

i am now attempting to use a random function so the lcd displays different values here is what i have

long randNumber;
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
//string array for when button is not pressed (Low)
char* stringLow[]={
  "Thankyou", "Thanks very much", "YEAH BABAY"
    "About Time!" "Get In There"};
//string array for when button is not pressed (High)
char* stringHigh[]={
  "HELP ME!", "Cmon Please", "Its cold Help!",
  "Cmon do something", "just push the button"};
const int analogInPin = A0;  // Analog input pin that the Button is attached to
const int analogOutPin = 9; // Analog output pin that the Servo is attached to

// read the value of the button to see if it is high or low
int sensorValue = 0;        // value read from the pot
int outputValue = 0;        // output value to the LCD and Servo
void setup() {
  // initialize serial communications at 9600 bps:
  Serial.begin(9600); 
  // tell arduino how many rows and collums lcd has
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("Press The Button!");
  randomSeed(analogRead(0));

}

void loop() {
  // read the analog in value:
  sensorValue = analogRead(analogInPin);            
  // map it to the range of the analog out:
  outputValue = map(sensorValue, 0, 1023, 0, 255);  
  // change the analog out value:
  analogWrite(analogOutPin, outputValue);

  for (int i = 0; i < 5; i++){
    Serial.println(stringHigh[i]);
    delay(500);
  }
  for (int i = 0; i < 5; i++){
    Serial.println(stringLow[i]);
    delay(500);
  } 

  if (outputValue < 20)
    //  if statement saying if the button is not pressed (0) then print one value 
  { 
    randNumber = random (stringHigh)
      lcd.print (randNumber);
  }
  else
    // when button is pressed say this value

  {
    randNumber = random (stringHigh)
      lcd.print (randNumber);
  }


  //set the cursor to the first point on the lcd to display values
  lcd.setCursor(0, 1);
  lcd.clear;
