I would like to calculate the following number of data in sample_data.xlsx.

  1. The number of entries whose title starts with [good] and whose level is High
  2. The number of entries whose title starts with [good] and whose level is Ligh
  3. The number of entries whose title does not begin with [good] and whose level is High
  4. The number of items whose title does not start with [good] but whose level is Ligh

But there are some errors.
