The IF and double IF statement
Our mission is to add the word BIG
if the area is greater than or equal to 300 m2
If not, we leave the cell empty.
To add the word MEDIUM and SMALL, we nest another if statement.
The conditions are applied from left to right.
If the first condition matches the value of the cell, the others are ignored.
If not, the second condition is applied, then the third ...etc.
