I2C LCD compiling error

This is my first post, and ill make it clear i am new to both electronics and coding.

I have a UNO board and a Ebay special LCD screen

I2C Address: 0x27

Backlight (White character on Blue background)

Supply voltage: 5V

Size: 82x35x18 mm

Come with IIC interface, which can be connected by DuPont Line

Package Include
1 X IIC/I2C/TWI 1602 Serial LCD Module

and the wired version of a DHT 22 sensor

So…

I downloaded the library “New Liquid Crystal” from https://bitbucket.org/fmalpartida/new-liquidcrystal/downloads (Downloaded repository and installed in the /documents/arduino/library folder. I then cut the original Liquid Crystal library out of the arduino directory and moved it elswhere.

I also downloaded the DHT library from Adafruit and installed in the same way.

I mashed the example code for I2C Hello world and the DHT sensor together and uploaded it. Everything worked fine except for some flakey bread board connections.

I then worked on something else for a while. When i tried to reupload the same code, it would not compile.

#include <LiquidCrystal_I2C.h>
#include <DHT.h>
#include <Wire.h>


#define BACKLIGHT_PIN     13
#define DHTTYPE DHT21   // DHT 21 (AM2301)
#define DHTPIN 2     // what digital pin we're connected to
DHT dht(DHTPIN, DHTTYPE);
LiquidCrystal_I2C lcd(0x27);  // Set the LCD I2C address









void setup()   /*----( SETUP: RUNS ONCE )----*/
{
pinMode ( BACKLIGHT_PIN, OUTPUT );
digitalWrite ( BACKLIGHT_PIN, HIGH );

lcd.begin(16,2);         // initialize the lcd for 20 chars 4 lines, turn on backlight
lcd.backlight();
  dht.begin();

}/*--(end setup )---*/

void loop()   /*----( LOOP: RUNS CONSTANTLY )----*/
{

  // Reading temperature or humidity takes about 250 milliseconds!
  // Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor)
  float h = dht.readHumidity();
  // Read temperature as Celsius (the default)
  float t = dht.readTemperature();
  // Read temperature as Fahrenheit (isFahrenheit = true)
  float f = dht.readTemperature(true);


  }
  
lcd.setCursor(0,0);

lcd.print("Temp ");
lcd.print(t);
lcd.print((char)223);
lcd.print("C");
  

lcd.setCursor(0,1);
lcd.print("Humidity ");
lcd.print(h);
lcd.print("%");


  delay(2000);

  This report would have more information with

  enabled in File > Preferences.

The errors with the DHT parts are not realy the issue, its the “error: ‘lcd’ does not name a type” instances that have me baffled.

I have tried google for a couple of hours and have to say im more confused than when i started.

When i made a new sketch in exactly the same way as the first time, it compiled no problem.

#include <DHT.h>
#include <Wire.h> 
#include <LiquidCrystal_I2C.h>



#define BACKLIGHT_PIN     13
#define DHTTYPE DHT21   // DHT 21 (AM2301)
#define DHTPIN 2     // what digital pin we're connected to
DHT dht(DHTPIN, DHTTYPE);
LiquidCrystal_I2C lcd(0x27);  // Set the LCD I2C address







void setup()
{

  // Switch on the backlight
  pinMode ( BACKLIGHT_PIN, OUTPUT );
  digitalWrite ( BACKLIGHT_PIN, HIGH );
  
  lcd.begin(16,2);               // initialize the lcd 
  dht.begin();                  // intitalise DHT sensor


  lcd.home ();                   // go home
  lcd.print("DHT22 Sensor");  
  lcd.setCursor ( 0, 1 );        // go to the start of next line
  lcd.print ("Temp/Humidity");
  delay ( 1000 );
}

void loop()
{
  // Reading temperature or humidity takes about 250 milliseconds!
  // Sensor readings may also be up to 2 seconds 'old' (its a very slow sensor)
  float h = dht.readHumidity();
  // Read temperature as Celsius (the default)
  float t = dht.readTemperature();
  // Read temperature as Fahrenheit (isFahrenheit = true)
  float f = dht.readTemperature(true);


lcd.setCursor(0,0);         //lcd start of first line

lcd.print("Temp ");     
lcd.print(t);               //lcd display temperature value
lcd.print((char)223);       //degree symbol(°)
lcd.print("C");

lcd.setCursor(0,1);         //lcd start of second line
lcd.print("Humidity ");
lcd.print(h);               //lcd display humidity value
lcd.print("%");
  
   delay (200);            //delay between reads
}
Sketch uses 7,164 bytes (22%) of program storage space. Maximum is 32,256 bytes.
Global variables use 356 bytes (17%) of dynamic memory, leaving 1,692 bytes for local variables. Maximum is 2,048 bytes.

Im at a loss as to what ive done??

Thanks in advance for any help i receive, playing with this stuff would be impossible for someone like me without the vast amount of knowledge freely given here.

Please use the indents and spaces and brackets always in the same way.

Try the auto-text-layout-format tool. It is in the menu : Tools / Auto Format Ctrl+T
When you do that, you immediately see the problem when you scroll down.

AH HA. Its been driving me mad for days. Thank you very much, compiled no problems.
