Why won't this code break?

Using Arduino Programming Questions
#1

Hi, fairly new to the world of coding and Arduino.

Have been messing around with this piece of code for hours and cannot figure out why it wont break when # is pressed on the keypad.

if(key == 'B'){
  keyB = true;
  
  while(keyB=true){
  lcd.clear();
  lcd.setCursor(0,0);
  lcd.print("Power generated:");
  lcd.print(power2);
  lcd.setCursor(0,1);
  lcd.print("Power needed:");
  lcd.print(load);
  delay(2000);
  lcd.clear();
  lcd.setCursor(0,0);
  lcd.print("Power used:");
  lcd.setCursor(0,1);
  lcd.print("Power deficit:");
  delay(2000);
  
  if(key == '#'){
    keyB=false;
    break;
    }
  }
}

Its probably something simple, but I cannot pick it. Any help would be appreciated.
Cheers

The test for # is inside the if that already established that key is 'B'. Key isn't read again in the while loop, hence the symptom you see.

Ah, thanks a lot!

  while(keyB=true){

= != ==
