need help in tem/hum sensor .. trying to get it word

i could not fix the mistake … could u help me please .

// Read temperature/humidity from sensor and display on LCD screen

#include <SoftwareSerial.h>
#include <Sensirion.h>

#define lcdTxPin 2
#define sensorDataPin 3
#define sensorClockPin 4

float temperature;
float humidity;
float dewpoint;

Sensirion tempSensor = Sensirion(sensorDataPin, sensorClockPin);
SoftwareSerial LCD = SoftwareSerial(0, lcdTxPin);

void setup() {

LCD.begin(9600);
Serial.begin(9600);
backlightOn();
clearLCD();
LCD.print(" Starting…");
}

void loop() {

delay(3000);

// get the temp/humidity
tempSensor.measure(&temperature, &humidity, &dewpoint);

goTo(0);
LCD.print(" Temp Humidity");
goTo(16);
LCD.print(" “);
serialPrintFloat(LCD, convertToFahrenheit(temperature));
LCD.print(” “);
serialPrintFloat(LCD, humidity);
LCD.print(”%");
}

// Prints a floating point number to the screen
void serialPrintFloat(SoftwareSerial output, float f){
output.print((int)f);
output.print(".");
int decplace = (f - (int)f) * 10;
output.print(abs(decplace));
}

// Convert celsius to fahrenheit
float convertToFahrenheit(float c) {
return ((9.0 / 5.0) * c) + 32.0;
}

// Sets the cursor to the given position
// line 1: 0-15, line 2: 16-31, 31+ defaults back to 0
void goTo(int position) {
if (position < 16) {
serCommand(); //command flag
LCD.print((position+128), BYTE);
} else if (position < 32) {
serCommand(); //command flag
LCD.print((position+48+128), BYTE);
} else {
goTo(0);
}
}

// Resets the display
void clearLCD() {
serCommand();
LCD.print(0x01, BYTE);
}

// Turns the backlight on
void backlightOn() {

LCD.print(157, BYTE);
}

// Turns the backlight off

// Initiates a function command to the display
