Hi, I was wonder how can I know the corresponding value of a certain value. For example, if I have two columns X and Y how can I know the value in X of the maximum Y value?

Thanks in advanced

GG

It all depends on which values. In your specific example, lets assume that you have X in col(A) and Y in column(B), then the following is how you find X at Max Y:

sum(col(B));
col(A)[sum.imax]=;
