Error: expected primary-expression before '.' token

I'm having trouble with the coding side of my project. Here is my code:

~~~~~~~~~~
void setup() {
  ~~~~~~~~~~
  const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
  LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
  lcd.begin(16, 2);

  Serial.begin(9600);
}


void loop() {

  ~~~~~~~
  lcd.print(Tc);
  lcd.setCursor(00, 1);
  lcd.print(Tf);

  delay(1000);
~~~~~~~~~~~~~~~~~~~~~~

When I try to verify it, I get the error:

exit status 1
expected primary-expression before '.' token

What am I doing wrong?

I apologize, but I removed most of the code after 12 hours and helpful responses because I am using it for part of a competition, and I don't want competitors to be able to use it. Sorry. (The removed code is represented by ~~~~~~~~.)

Line 2 code in your sketch is the issue.

Look at the examples in the reference that show you how to declare the lcd object.

3 
#define lcd

lcd is defined as having no value

So, as far as the compiler is concerned it sees

 lcd.print(Tf);

as

 .print(Tf);

hence the error

Did you actually mean to declare an instance of the LCD library with the name lcd ?
You have actually done that in setup()
  LiquidCrystal lcd(rs, en, d4, d5, d6, d7);but that means you can only use it in setup(). Move the declaration outside of any function to make it available globally

I was able to make it work by deleting my 2nd line, and moving LiquidCrystal lcd(rs, en, d4, d5, d6, d7); into the loop().

Thanks everyone!
