Here is a TEST
Something that may have alluded you:

  //******************************                        5   s e c o n d   T I M E R
  //if the 5 second TIMER is enabled, has it expired ?
  if (doBlink == false && currentMillis - previousMillis >= 5000)
  {
    //enable the 80ms and 30 second TIMERs
    doBlink = true;

    //restart the 80ms TIMER
    previousMillis = millis();

    //restart the 30 second TIMER
    previous30secondMillis = millis();
  }

The above was taken from the last sketch offered.

What would result if we just had:


  //******************************                        5   s e c o n d   T I M E R
  //has the 5 second TIMER expired ?
  if (currentMillis - previousMillis >= 5000)
  {
    //enable the 80ms and 30 second TIMERs
    doBlink = true;

    //restart the 80ms TIMER
    previousMillis = millis();

    //restart the 30 second TIMER
    previous30secondMillis = millis();
  }
