need help programing switches

hi there, I need help to change my code. at the moment I have two switch’s. one is couting up and one is counting down, how can I change the code that both switches need to be pressed at the same time for the number on the lcd to increase? my switches are wired into port 8 and the other into 9 on the arduino.
this is the code im using, thanks

int sw1 = 8;
int sw2 = 9;
int count = 0;
#include <LiquidCrystal.h>
LiquidCrystal lcd(7,6,5,4,3,2);

void setup()
{
lcd.begin(16, 2);
lcd.print(“Counter”);
pinMode(sw1,INPUT);
pinMode(sw2,INPUT);
digitalWrite(sw1,HIGH);
digitalWrite(sw2,HIGH);
}

void loop()
{
if(digitalRead(sw1) == LOW)
{
count++;
lcd.setCursor(0, 1);
lcd.print(count);
delay(400);
}
if(digitalRead(sw2) == LOW)
{
count–;
if(count < 0)
count = 0;
lcd.setCursor(0, 1);
lcd.print(count);
delay(400);
}

}

What about :

if(digitalRead(sw1) == LOW && digitalRead(sw2) == LOW ) { // increase number on the lcd . . . . . . }

where about would I post that in the code? im new to the arduino so still only getting used to the code wrighting

just got it there, thanks for the help

If one switch causes an increase, and one causes a decrease, what is the point of using both switches to cause an increase? How will you then cause a decrease?
