3) =OFFSET($D$3,0,0,COUNTA($D$3:$D$10),1)
4) OK

Let's breakdown the formula.

The OFFSET function in Excel is used to create a reference to a range of cells that is offset from a starting cell by a certain number of rows and columns. $D$3 is the starting cell reference.
It refers to cell $D$3, which is the starting point for the range.
0 is the number of rows to offset. Since it is 0, the range will start from the same row as the starting cell, which is D3.
0 is the number of columns to offset. Again, it is 0, so the range will start from the same column as the starting cell, which is column D.
1 is the number of columns in the resulting range. It indicates that the resulting range will have 1 column.

COUNTA($D$3:$D$10) is a function that counts the number of non-empty cells in the range D3:D10. It returns a numeric value representing the count of non-empty cells.

Putting it all together, the formula creates a range reference that starts from cell D3 and covers a certain number of rows and 1 column. The number of rows is determined by the count of non-empty cells in the range D3:D10. The resulting range is dynamic and adjusts automatically if the number of non-empty cells in the range changes.
