Doing the conditional sum of differences between rows

[Olbap]

Hi,

I am trying to obtain the sum of the differences between two rows column by column. I have two criteria to choose the column to compare. The first one is to have the word "Rank" in the heading of the column, this seems to work when I look to the calculation step by step. The second criterion is to skip columns where the difference gives an error because of a non-numeric value.

I figured the following function but somehow it doesn't work (I do Ctrl+Shift+Enter after editing) and I always get a zero.

=SUM(IF(AND($CT$6:$DF$6="Rank",ISERR(CT8:DF8-CT9:DF9)=FALSE),CT8:DF8-CT9:DF9))

Any idea of what is going wrong?

Thanks in advance!

Thanks Yogeshmaney. The problem is that I want the function to check if there is an error at each column and if not, take the difference between the values in the rows and sum it.

Here is a small part of my table:

Here I should get a 4 from the first column and a 23 from the fourth column and nothing for the last. At the end my function sould give 28 but I get a zero. Maybe this is because the last column gives a #Value error? I don't know how to tell it to skip that last column and do the sum for the others? Any idea?

Any other ideas?
