Functions are modifiers used to manipulate the data. These are predefined by the software itself, and must be used to perform specific functions.
IsNull(): This is used to determine if the value of an object is null. It will return true if the value is null, or False if the object contains data
Sum(): Sums numeric data in a formula
If/Then/Else(): This combination of functions is used together to compare different objects and/or values to one another, using true/false logic

- If the data is numeric, this will return the lowest number
