detect which button is pressed and use that value in switch statement?

let's hope this works, first time posting code (using leds for now, easier to wire up in testing). Also a lot of serial prints, to verify if variables are set properly:

//setting the pins
int ledPin1 = 13;
int ledPin2 = 2;
int buttonPin1 = 7; //replace with relays later
int buttonPin2 = 8; //replace with relays later


//setting the variables
int button1State; //detect button state pressed.
int button2State;
int channelSelect = 0;

void setup() { 

//Led for channel select
 pinMode(ledPin1, OUTPUT);
 pinMode(ledPin2, OUTPUT);
// pinMode(ledPin3, OUTPUT);
// pinMode(ledPin4, OUTPUT);

//channel select switches
 pinMode(buttonPin1, INPUT_PULLUP);
 pinMode(buttonPin2, INPUT_PULLUP);
//  pinMode(buttonPin3, INPUT_PULLUP);
//  pinMode(buttonPin4, INPUT_PULLUP);

//Serial for displaying the values during debugging
Serial.begin(9600);

}


void loop() {

// output to serial monitor to validate if variables are set properly
Serial.print("Channelselect value:");
Serial.print(channelSelect);
Serial.print(" - ");
Serial.print("Button1state: ");
Serial.print(button1State);
Serial.print(" - ");
Serial.print("Button2state: ");
Serial.print(button2State);
Serial.print("\n");

int button1State = digitalRead(buttonPin1); //validate button1 pressed
int button2State = digitalRead(buttonPin2); //validate button2 pressed

//verify buttonstate and set the channelselect value to trigger case
   if(button1State == 1)
       {
       channelSelect = 1;
     }
     if(button2State == 1)
       {
       channelSelect = 2;
     }

switch(channelSelect)
   {
     case 0:
       digitalWrite(ledPin1, HIGH);
       digitalWrite(ledPin2, LOW);
       break;
     case 1:
       digitalWrite(ledPin1, LOW);
       digitalWrite(ledPin2, HIGH);
       break;
   }
}
