I need to start in a given cell and enter a formula, then copy that formula to the next cell up if it is blank. For example, I'll start in cell N33 and want to enter the formula N33-L33, then move to the next cell up N32 and enter the formula N32-L32. I want to continue this until the cell above is filled (which is my header). The starting cell will vary worksheet to worksheet, but I'll always place the cursor in the "starting blank cell", be it N33 or N100 or N12. Once I have the cursor in the starting cell, I'll run the macro.
