ELEGOO UNO R3 2.8 Inches TFT Touch Screen with SD Card Socket Problem

Here is the full code.

Note that the configuration mentioned is left as is since the LCD Shield is being used:

// **** IF USING THE LCD BREAKOUT BOARD, COMMENT OUT THIS NEXT LINE. ****
// **** IF USING THE LCD SHIELD, LEAVE THE LINE ENABLED: ****

//#define USE_Elegoo_SHIELD_PINOUT 1

[code]
// IMPORTANT: ELEGOO_TFTLCD LIBRARY MUST BE SPECIFICALLY
// CONFIGURED FOR EITHER THE TFT SHIELD OR THE BREAKOUT BOARD.
// SEE RELEVANT COMMENTS IN Elegoo_TFTLCD.h FOR SETUP.
//Technical support:goodtft@163.com

#include <Elegoo_GFX.h> // Core graphics library
#include <Elegoo_TFTLCD.h> // Hardware-specific library
#include <SD.h>
#include <SPI.h>

// The control pins for the LCD can be assigned to any digital or
// analog pins...but we'll use the analog pins as this allows us to
// double up the pins with the touch screen (see the TFT paint example).
#define LCD_CS A3 // Chip Select goes to Analog 3
#define LCD_CD A2 // Command/Data goes to Analog 2
#define LCD_WR A1 // LCD Write goes to Analog 1
#define LCD_RD A0 // LCD Read goes to Analog 0
#define PIN_SD_CS 10 // Elegoo SD shields and modules: pin 10

#define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin

// When using the BREAKOUT BOARD only, use these 8 data lines to the LCD:
// For the Arduino Uno, Duemilanove, Diecimila, etc.:
// D0 connects to digital pin 8 (Notice these are
// D1 connects to digital pin 9 NOT in order!)
// D2 connects to digital pin 2
// D3 connects to digital pin 3
// D4 connects to digital pin 4
// D5 connects to digital pin 5
// D6 connects to digital pin 6
// D7 connects to digital pin 7
// For the Arduino Mega, use digital pins 22 through 29
// (on the 2-row header at the end of the board).

// Assign human-readable names to some common 16-bit color values:
#define BLACK 0x0000
#define BLUE 0x001F
#define RED 0xF800
#define GREEN 0x07E0
#define CYAN 0x07FF
#define MAGENTA 0xF81F

#define WHITE 0xFFFF

NEVER MIND!!!! As posted earlier, I misread this and didn't notice the define was commented out, and I should have "uncommented" it!

Note that the configuration mentioned is left as is since the LCD Shield is being used:

// **** IF USING THE LCD BREAKOUT BOARD, COMMENT OUT THIS NEXT LINE. ****
// **** IF USING THE LCD SHIELD, LEAVE THE LINE ENABLED: ****

//#define USE_Elegoo_SHIELD_PINOUT 1

Got past the original error message, and have gotten a new one that I am currently researching.

Sorry if I confused anyone with my confusion!

That's ok

Without confusion we'd be sure of everything
