I have a formula in B25. I put it there. I like it. It is the same formula that is in b24, with the references adjusted one row, because I've been dragging it down. I add data to the bottom of the sheet, and drag down the formula. Now it seems that the formula copies down on its own, after I enter a value in an adjacent cell. I can't figure out why it is doing this, even though it is convenient. Any ideas? TIA
