user3454: I want the bottom row of my LCD to display the counting function and include text:
lcd.setCursor(0, 1);
lcd.print("Launch in"millis()/1000);

But it comes out with an error, what part is wrong?

user37: Change the last line to:
lcd.print("Launch in " + (millis() / 1000));

The + concatenates the string Launch in with the number that results from millis() / 1000.

user1566: lcd.setCursor(0, 1);
lcd.print("Launch in ");
lcd.print(millis()/1000);


user1407: The last line in the code you provided won't compile.
The lcd.print() function expects a char, byte, int, long or string (taken from the LiquidCrystal docs) and you're trying to combine a string and an int which the compiler isn't going to understand.
The easiest way to print both would be to have two lcd.print statements:
lcd.print("launch in ");
lcd.print(millis()/1000);

Most of this is taken from quickly googling displaying time on an lcd screen.
