How does the `range_lookup` argument in `VLOOKUP` affect the use of `IFERROR`?

Using `TRUE` (approximate match) in `VLOOKUP` can sometimes lead to unexpected results and more frequent errors, especially if the data isn't sorted correctly. This increases the likelihood of needing `IFERROR` to handle errors caused by incorrect approximate matches. It's generally best practice to use `FALSE` (exact match) whenever possible to minimize errors and simplify error handling.
