How do i add this styuff t0 the code

I wannna make it so the weight is read and is on the LCD, one tatcile switch lowers the weight needed to buzz the buzzer and vise versa

#include <LiquidCrystal.h>
#include <Wire.h>

int IN1 = A0;
int IN2 = A1;
#define HX711_SCK 8
#define HX711_DT 7
const int buzzer = 13;

int over_val;
int data;
int g_weight;
int Weight;

void setup()
{
pinMode(buzzer, OUTPUT);

pinMode(IN1, INPUT);
pinMode(IN2, INPUT);
Init_Hx711();
Serial.begin(9600);
Serial.print("Ready!\n");
Get_Maopi();
}

void loop()
{
if (digitalRead(IN2) == LOW)
{
data = Weight;
}

if (digitalRead(IN1) == LOW)
{
over_val = g_weight;
}

if (g_weight > over_val)
{
Serial.println("overload");
digitalWrite(buzzer, HIGH);
}

delay(50);
}

long HX711_Buffer = 0;
long Weight_Maopi = 0, Weight_Shiwu = 0;

//****************************************************
//初始化HX711
//****************************************************
void Init_Hx711()
{
pinMode(HX711_SCK, OUTPUT);
pinMode(HX711_DT, INPUT);
}

//****************************************************
//获取毛皮重量
//****************************************************
void Get_Maopi()
{
HX711_Buffer = HX711_Read();
Weight_Maopi = HX711_Buffer / 100;
}

//****************************************************
//称重
//****************************************************
unsigned int Get_Weight()
{
HX711_Buffer = HX711_Read();
HX711_Buffer = HX711_Buffer / 100;

Weight_Shiwu = HX711_Buffer;
Weight_Shiwu = Weight_Shiwu - Weight_Maopi; //获取实物的AD采样数值。

Weight_Shiwu = (unsigned int)((float)Weight_Shiwu / 4.11);
//计算实物的实际重量
//因为不同的传感器特性曲线不一样，因此，每一个传感器需要矫正这里的4.30这个除数。
//当发现测试出来的重量偏大时，增加该数值。
//如果测试出来的重量偏小时，减小改数值。
//该数值一般在7.16左右。因传感器不同而定。
//+0.05是为了四舍五入百分位

return Weight_Shiwu;
}

//****************************************************
//读取HX711
//****************************************************
unsigned long HX711_Read(void) //增益128
{
unsigned long count;
unsigned char i;
// bool Flag = 0;

digitalWrite(HX711_DT, HIGH);
delayMicroseconds(1);

digitalWrite(HX711_SCK, LOW);
delayMicroseconds(1);

count = 0;
while (digitalRead(HX711_DT));
for (i = 0; i < 24; i++)
{
digitalWrite(HX711_SCK, HIGH);
delayMicroseconds(1);
count = count << 1;
digitalWrite(HX711_SCK, LOW);
delayMicroseconds(1);
if (digitalRead(HX711_DT))
count++;
}
digitalWrite(HX711_SCK, HIGH);
count ^= 0x800000;
delayMicroseconds(1);
digitalWrite(HX711_SCK, LOW);
delayMicroseconds(1);

return (count);
}

Use:

pinMode(xx, INPUT_PULLUP);

instead of:

pinMode(xx, INPUT);

for starters.
Next, FORMAT THE CODE with </> button please. Do a Ctrl-T in the IDE before copying.
