Main js lines/commands used:

    
      function checkSensor() {
        console.log("heello");
      //   console.log(checkSensor1(), checkSensor2());
        if (checkSensor1() & checkSensor2()) {
          alert('OK')
        } else {
          alert('ERROR')
        }
      }

      function checkSensor1() {
        let sensor1Value = document.querySelector("#sensor1").value;
        let sensorOK;
        if (sensor1Value < 10) {
          sensorOK = false;
          document.querySelector("#mark1").classList.remove("green");
          document.querySelector("#mark1").classList.add("red");
        } else {
          sensorOK = true;
          document.querySelector("#mark1").classList.remove("red");
          // document.querySelector('#mark1').style.backgroundColor = "orange"
          document.querySelector("#mark1").classList.add("green");
        }
        return sensorOK;
      }

      function checkSensor2() {
        let sensor2Value = document.querySelector("#sensor2").value;
        let sensorOK;
        if (sensor2Value < 10) {
          sensorOK = false;
          document.querySelector("#mark2").classList.remove("green");
          document.querySelector("#mark2").classList.add("red");
