In this lesson we'll practice wrapping our VLOOKUP functions in an IFERROR statement in order to return a custom value in cases where our lookup value cannot be located in our table array.

In this lesson we'll compare several different options for the table_array argument of a VLOOKUP function, including fixed cell references, column-only references, and named ranges.

In this lesson we'll practice writing a VLOOKUP function using an approximate match argument, in order to match values to predefined ranges (or "buckets"), rather than searching for exact matches.

In this lesson we'll use Excel's INDEX function to navigate to specific rows and columns within a given range.

In this lesson we'll practice using Excel's MATCH function to return the position of a given value or text string within a range of cells.
