When you want to use the VLOOKUP function, you need to set up a lookup column (in the table that you have made). a) How must the items in the lookup column be arranged if they are numbers? b) How must the items in the lookup column be arranged if they are words? Vertically, in columns, arranged in alphabetical order (words) or low number to high number(Numbers) to get the correct answer. c) Why are the columns set up this way? Because this function searched a specified part of a worksheet for data starting in the first column, The V stands for vertical, or the data stored in columns rather than rows. It looks up the greatest value that doesn't exceed the specified value anywhere in a table or a group. The lookup column also uses a true lockup type so the column containing these values muyst be in ascending order
