How do I add additional sensors?

Projects Programming
15 
int pumpPin1 = 12;
int pumpPin2 = 13;
int pumpLEDPin = 11;
int sensorPin1 = A1;
int sensorPin2 = A2;
int sensorPin3 = A3;
int sensorPin4 = A4;
int sensorPin5 = A5;
int sensorPinValue;
// variables
sensorPinValue = analogRead(sensorPin1);
sensorPinValue = analogRead(sensorPin2);
sensorPinValue = analogRead(sensorPin3);
sensorPinValue = analogRead(sensorPin4);
sensorPinValue = analogRead(sensorPin5);

I get the error message? where have I done wrong?
