RE: How to use a v look up function
Searches for a value in the leftmost column of a table, and then returns a value in the same row from a column you specify in the table. Use VLOOKUP instead of HLOOKUP when your comparison values are located in a column to the left of the data you want to find.
The V in VLOOKUP stands for "Vertical."
VLOOKUP(lookup_value,table_array,col_index_num,range_lookup)
Lookup_value is the value to be found in the first column of the array. Lookup_value can be a value, a reference, or a text string.
Table_array is the table of information in which data is looked up. Use a reference to a range or a range name, such as Database or List.
If range_lookup is TRUE, the values in the first column of table_array must be placed in ascending order: ..., -2, -1, 0, 1, 2, ..., A-Z, FALSE, TRUE; otherwise VLOOKUP may not give the correct value. If range_lookup is FALSE, table_array does not need to be sorted.
You can put the values in ascending order by choosing the Sort command from the Data menu and selecting Ascending.
The values in the first column of table_array can be text, numbers, or logical values.
Uppercase and lowercase text are equivalent.
