What do you wish to change? The target cell starts in column D and goes down from row 56 to ??. Having done this loop j changes to 5 i.e column E and changes row from 56 to ??.

The "ByChange" stays constant i.e. row number is constant 41 and 44 only column changes from D to E after the row loop i has gone through all values.

The same goes for the constraint, constant row number and after all i values have been tested column changes from D to E.

Since you can't upload the file try to explain what you hope to achieve after each change in i and after a change in j.
