The LOOKUP functions search the table array to find specific information.
For VLOOKUP (vertical lookup), the table_array must contain at least two columns of data.
For HLOOKUP (horizontal lookup), the table_array must contain at least two rows of data.
Other arguments in the LOOKUP functions that make use of the table array:
lookup _value: located in the first column or row of the table_array.
index_num: The number of the column or row in the table_array that contains the data you are searching for.
