Using BMP280 sensor to control servos. Need some guidance with coding

My apology for troubling you again. I tried to use the library and add altitude check and the servo code to it. However, I got an error message when I compiled the codes. I hope you can assist me on this. Below is the code and also the error message.

int servoPin1 = 9;
int servoPin2 = 10;
int servoPin3 = 11;
int greenLed = 13;
