    Combining IF, ISERROR, and possibly OR or AND functions

    I need help combining multiple functions in a cell to always return a null if any of the conditions are null or result in an error.

    I have data in column B, if I do a vlookup in column C to an array that sits elsewhere I want any errors (#N/A) to display as null - I can do that. If a particular row in column B is blank then I want the vlookup result to also display as null - I can do that.

    But I can't figure out how to combine them, whether it's an OR or AND function combined with IF and ISERROR or something else entirely.

    I think the attached sample spreadsheet will illustrate better what I'm trying to get at. Thanks in advance for the help.

    In Excel 2007 you can use IFERROR function like this in row 5 copied down

    =IFERROR(VLOOKUP(B5,K$4:L$9,2,0),"")

    The unfortunate bit is that I'm on 2003.

    From your example i couldn't really work out what you wanted but is this close?
    =IF(B5="","Null",IF(ISERROR(VLOOKUP(K5,B5:E10,1,FALSE)),"Null",VLOOKUP(K5,B5:E10,1,FALSE)))

    With the correct cell references...that's it!! I was using that but kept adding an obscene amount of parentheses so it wouldn't work for me yesterday.
    Here's my result if anyone is interested. =IF(B5="","",IF(ISERROR(VLOOKUP(B5,$K$4:$L$9,2,FALSE)),"",VLOOKUP(B5,$K$4:$L$9,2,FALSE)))

    Thank you, thank you, thank you!

    I would suggest using ISNA instead of ISERROR, as that will mask all errors.

    Here's another way that avoids using the VLOOKUP formula twice:

    =IF(B5="","",IF(COUNTIF($K$4:$L$9,B5)=0,"",VLOOKUP(B5,$K$4:$L$9,2,FALSE)))

    Hope this helps.
