Custom functions need to be made using a VBA language, or Visual Basic for Applications. Instead of a Sub statement, you will need a Function statement. To begin adding a function you will begin with a Function statement and close with an End Function statement.

In addition to this function name, you will also need one or more arguments. A function procedure must contain one or more VBA statements. These VBA statements are responsible for making any decisions or calculations put forth by your argument.
