There are four (4) steps to the VLOOKUP function, each separated by a comma.
1. Value: The common identifier that can be used to connect both data-sets.
2. Table: The table (or range) that contains the data you want to bring over.
3. Col_Index: Identifies which specific column from the table (or range) you want to bring over.
4. Range_Lookup: TRUE = Approximate Match, FALSE = Exact Match.
