The evaluation errors are as follows:
Missing value: This error occurs when the cell referred in a formula does not hold a value
Reference out of range: This error occurs when a reference is outside the scope of the spreadsheet
Circular reference: This error occurs when a cell is referring to itself, directly or indirectly
Division by zero: This error occurs when the denominator in a division expression is zero
There is also the syntax error that occurs when the user inputs a syntactically incorrect formula.
