Momentary switch to control left and right keyboard inputs

[goodracing112]

so I have a three way momentary switch hooked up to pin 14 for left pin 18 for right and then center is on the ground trying to get it to control left and right keyboard input or any input really with this code i get just pretty uncontrolled input left and right ill press right and it may work it may not or it may just go left for whatever time it feels like could it be an issue with the switch or connections or just bad code?

#include <Keyboard.h>

// Define the input pins  
const int inputLeft = 14; // Input for left key  
const int inputRight = 18; // Input for right key

// Variables for debouncing and state change detection  
bool lastStateLeft = LOW;
bool currentStateLeft = LOW;
bool lastStateRight = LOW;
bool currentStateRight = LOW;
unsigned long lastDebounceTimeLeft = 0;
unsigned long lastDebounceTimeRight = 0;
const unsigned long debounceDelay = 50; // Debounce time in milliseconds

void setup() {
  // Initialize the Keyboard library  
  Keyboard.begin();

  // Set the input pins as inputs  
  pinMode(inputLeft, INPUT);
  pinMode(inputRight, INPUT);
}

void loop() {
  // Read the current state of the inputs  
  int readingLeft = digitalRead(inputLeft);
  int readingRight = digitalRead(inputRight);

  // Debounce the left input  
  if (readingLeft != lastStateLeft) {
    lastDebounceTimeLeft = millis();
  }
  if ((millis() - lastDebounceTimeLeft) > debounceDelay) {
    if (readingLeft != currentStateLeft) {
      currentStateLeft = readingLeft;
      if (currentStateLeft == HIGH) {
        Keyboard.press(KEY_LEFT_ARROW);
      } else {
        Keyboard.release(KEY_LEFT_ARROW);
      }
    }
  }
  lastStateLeft = readingLeft;

  // Debounce the right input  
  if (readingRight != lastStateRight) {
    lastDebounceTimeRight = millis();
  }
  if ((millis() - lastDebounceTimeRight) > debounceDelay) {
    if (readingRight != currentStateRight) {
      currentStateRight = readingRight;
      if (currentStateRight == HIGH) {
        Keyboard.press(KEY_RIGHT_ARROW);
      } else {
        Keyboard.release(KEY_RIGHT_ARROW);
      }
    }
  }
  lastStateRight = readingRight;
}
