Hi,
The mistake could be the #DIV/0! error , or a #REF! error
Explanation
When changing the data in a cell that’s used in a formula, a #DIV/0! Error can occur when the formula attempts to divide a number by 0 or an empty cell. To rectify this, you will need to change the value of that cell to a value not equal to 0. In some cases, the #REF! error could be displayed. This means that the formula refers to a cell that is not valid.
Hope this Helps!
