Conditional Formatting

[jkugizak]

Hello,

I have a range of data that I would like to conditionally format all cells that have an error to have white font. Unfortunately, I cannot use a function like this:

if(iserror(function,"",function))

because the formulas in this range are already too long to be able to duplicate for the 'value if false' argument. I have also tried using the conditional formatting tool by setting "Formula Is" equal to:
=ISERROR($A$1)
but this only whites out errors in cell A1 or column A (depending on what I selected.

I have pasted the formula below that is giving me the error if anyone has any ideas on how to modify the formula as well. It is basically an index match formula that is looking at several different data points on another worksheet and averaging them. Thanks in advance.

=AVERAGE(INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$2,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$3,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$4,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$5,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$6,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$7,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$13,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$8,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$9,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$10,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$11,SRD!$D$2:$DG$2,0)),INDEX(SRD!$D$4:$DG$351,MATCH($C18,SRD!$A$4:$A$351,0),MATCH(M$12,SRD!$D$2:$DG$2,0)))

If i select a range from lets say A1 to M40 and then go conditional formatting,
formula is =ISERROR(A1) then the formatting is applied to the entire range. ( in 2003)

(e.g. no $ sign)

This doesn´t work for you?
