    In O2, change formula to this:

    Copy down/right as needed. Problem is that the cells you see as blank, actually have zero-length strings. This confuses XL into thinking there's really a value, and so it's able to correctly do a MATCH. Solution then is instead of trying to just error trap, check first if cell's value is "".

    Im using a quartile formula by column. Problem is now the formula is returning a result when referencing a blank cell whereas before it wasnt doing this.

    The difference in Z11 and AA11 compared to Y11 is: M11 and N11 are truly empty, whereas L11 contains an invisible null string, which is probably the result of doing copy-and-paste-value of an explicit null string ("").

    Consequently, MATCH(N11,QUARTILE(N$2:N$11,{4,3,2,1,0}),-1) is evaluated as MATCH(0,...), which returns 3 because zero is less than or equal to QUARTILE(...,2). Similarly for MATCH(M11,...).

    In contrast, MATCH(L11,QUARTILE(L$2:L$11,{4,3,2,1,0}),-1) is evaluated as MATCH("",...), which returns #N/A. So IFERROR returns the null string ("").

    Either fix M11 and N11 et al to be consistent with L11 -- not a likely solution -- or change your formula as follows:


    PS.... I did not see Luke's response, apparently posted 4 hours earlier. My response is essentially a duplicate. But I'll let it stand because it contains a little more detail, which might be useful.
