i need help please see code and correct. please please

#include “HX711.h”
#include <Keypad.h>
#define DOUT 12
#define CLK 13
HX711 scale(DOUT,CLK);

float x, y ;

void setup()
{
pinMode(LED_BUILTIN, OUTPUT);
loop();
}

void high()
{
digitalWrite(LED_BUILTIN, HIGH);
loadcell();
}

void low()
{
digitalWrite(LED_BUILTIN, LOW);
{
setup();
}
}

void loadcell()

{
float calibration_factor = -396650;
scale.set_scale(-396650);
Serial.print(“wait 5 second:”);
Serial.print (scale.get_value(),3);
x = scale.get_value(),3;
Serial.print(“kg”);

if ( x == y )
{
Serial.print(" Please remove the bag is filled ");
low();
}
else{
loadcell();
}
}

void loop()
{
const byte ROWS = 4; //four rows
const byte COLS = 4; //four columns
char keys[ROWS][COLS] = {
{‘1’,‘2’,‘3’,‘A’},
{‘4’,‘5’,‘6’,‘B’},
{‘7’,‘8’,‘9’,‘C’},
{’*’,‘0’,’#’,‘D’}
};

byte rowPins[ROWS] = {5, 4, 3, 2};
byte colPins[COLS] = {9, 8, 7, 6};

Keypad keypad = Keypad( makeKeymap(keys), rowPins, colPins, ROWS, COLS );
char key = keypad.getKey();
if (key)
{
Serial.print(“keypressed is =”);
Serial.print(key);
high();
x = key;
}

}

What you want to correct in code, what is aim of your code?
