I have 2 fixed cells C1 and C4
I have a column of cells D1 to D6
For each cell, D1 to D6, copy to C1 and then copy the result of C4 to a new column E1 to E6. So the result of C4 using cell D1(in C1) is shown in cell E1, the result of C4 using cell D2 (in C1) is shown in cell E2 and so on.
Then copy the column E1:E6 to the next free column. If F;G;H are filled, then the result would be pasted into column I1:I6.
