It's pretty exciting to see your macro  coming alive in Excel. It is
exactly what I was looking for.

However, is it possible if you can help make one adjustment witht he macro?

When the macro replaces the row  that has an X with the formulas  in row 3 (in
current case row 5), the formula doesn't flow instead it pastes the same source
in row 5.

Example:

When I drag dow a formula from cell A5 to cell A6 below the formula adjust to
the conditions of cell A6. So when a formula in A5 is = B5+C5 and it is dragged
to cell A6 it changes to =B6+C6 and so on. I would like to have this function
applied in my macro.

Right now when I run the macro it doesn't adjust to the following cell instead
it's looked to cell A5. So any cell down the row A6, A7, A9, A12, etc, have the
same formula from as cell A5. Can you please help me adjust this macro so when
it is replaced by the formula down the rows  it adjusts accordingly?

Hey I can thank you enough for your help.

Here is how the current macro loolks for your reference.
