  • #NUM!: It will occur if your formula contains an invalid percentage.
  • #NAME?: If you type incorrect values in the formula, like a misspelling of a function. To correct it, write proper formula names.
  • #REF!: You may find this error if you are referencing an invalid cell. Also, it will occur if you have deleted a cell that is needed for the formula. To rectify this, select the correct cell references.
