What Is IFERROR? This function was created by Microsoft in Excel 2007 and therefore does not exist in the 2003 version of Excel. Its purpose is to prevent a formula from outputting an error (#N/A, #DIV/0, etc...). This can be helpful in preventing formulas dependent on other formulas (such as a subtotal) to error out.
Note that when there is an error condition in B5, ISERROR(B5) would return the result TRUE. Therefore, as a second step, in cell B5, you want to insert an IF function that uses an excel ISERROR function to find out if an error or a valid result would be returned by the VLOOKUP that you already tested.o improve the situation, you can place the VLOOKUP function in an IF function, and then let it execute only if the VLOOKUP function will not return an error. You can use the excel ISERROR function to detect any error condition and on that basis carry out your own action. This may sound more complicated than it is.
