Project One error msg should be cleared after correction

For Project 1 lesson 47-67 (file: index.js)
There is error.textContent = "Please enter values before submitting!" error message for warning usage.
A clearing up function error.textContent = "" should be added as well.

form.addEventListener('submit',(e) => {
  e.preventDefault();
  if (insertname.value && cost.value) {
    const item = {
      name: insertname.value,
      cost: parseInt(cost.value)
    };

    db.collection('expenses').add(item).then( res => {
      insertname.value = "";
      cost.value = "";
    })
    // should add this !!!
    error.textContent = ""
  } else {
    error.textContent = "Please enter values before submitting!"
  }
})
