LCD menu

Im trying to find a way to enter my code an LCD menu To enter the temperature and fan settings

#include "DHT.h"                        
#include                
#define DHTPin 2                        
LiquidCrystal lcd(1, 3, 4, 5, 6, 7); 
float tempC;  
int fanPin = 8;
int ledrPin = 13;
int ledvPin = 11;
int heatresestancePin = 12;
char buzzer = 9;


DHT dht;


void setup() {
 dht.setup(DHTPin);  
 lcd.begin(16,2);
 pinMode(fanPin, OUTPUT);
 pinMode(ledrPin, OUTPUT);
 pinMode(ledvPin, OUTPUT);
 pinMode(heatresestancePin, OUTPUT); 
                 
}
void loop() {

 float tempC = dht.getTemperature();
 float humi = dht.getHumidity();
 
 if (tempC >36)
{
digitalWrite(fanPin, LOW);

 digitalWrite(ledvPin, LOW);
 
digitalWrite(ledrPin, HIGH);


 for(int note=700;note<2000;note++)
   {
   tone(buzzer, note, 125);
   delay (1);
 }
 for(int note=2000;note>=700;note--)
 {
   tone(buzzer, note, 125);
   delay(1);
  


 }
}
else
{
{
digitalWrite(fanPin, HIGH);

 digitalWrite(ledvPin, HIGH);
 
digitalWrite(ledrPin, LOW);


 
}
if (tempC <37)
{
 digitalWrite(heatresestancePin, LOW);

}
else 
{
  digitalWrite(heatresestancePin, HIGH);
 
}
 lcd.setCursor(0,0);
 lcd.print("Temp: ");
 lcd.print(tempC);
 lcd.print(" C");
 lcd.setCursor(0,1);
 lcd.print("Humi: ");
 lcd.print(humi);
 lcd.print(" %");
  delay(2000);
}

}

OK, first things first.

You need to go and read the forum instructions so that you can go back and modify your original post - the "More -> Modify" option below the right hand corner of your post - to mark up your code as such using the "" icon in the posting window. Just highlight each section of code (or output) from the IDE and click the icon. In fact, the IDE has a "copy for forum" link to put these markings on for you so you then just paste it here in a posting window.

Do not attach it as a ".ino" file. People can usually see the mistakes directly and do not want to have to actually load it in their own IDE. And that would also assume they are using a PC and have the IDE running on that PC.

But don't forget to use the "Auto-Format" (Ctrl-T) option first to make it easy to read. If you do not post it as "code", it can be quite garbled and is always more difficult to read.
