Value of variable doesn't change - arduino

Question

I am writing this code for a photoresistor on the arduino. I am supposed to attach servos to the photoresistor so that it will work as a moving solar panel. However, upon running the code I note that the value of variable pos (which is supposed to store the angle having max amount of light) does not change. What can I do about it?
int val1, val2, temp = 1000;
int pos = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
int sensorValue = analogRead(A0);
int val = map(sensorValue, 0, 1023, 0, 100);
Serial.println(val);
for(int i=0; i<180; i++){
val1 = map(sensorValue, 0, 1023, 0, 100);
if(val1 <= temp){
temp = val1;
pos = i;
}
delay(15);
}
Serial.println(pos);
delay(1000);
}

As #datafiddler suggested you need to ad the analogRead into the for loop.
Some things I would change in order to have a faster and cleaner code:
change the initialized temp to 100
delete val2
delete code before for loop
longer delay in for loop
here the edited code:
int val = 0;
int temp = 100;
int pos = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
//move servo to pos = 0
for(int i = 0; i < 180; i++){
val = analogRead(A0)
val = map(val, 0, 1023, 0, 100);
if(val <= temp){ //save minimum
temp = val;
pos = i; //save position
}
//move servo
delay(100); //try out what works best with the used servo
}
Serial.println(pos);
delay(1000);
}
