I'm looking a way to count or subtract two numbers if any on cells , if
there is a number, or 0, in a different cell.

N7 is the cell for the formula,
H7 the one if number found then
subtract L7-H7, but if there is no number on
L7, just show the same number of H7 on N7.

Any hint will be helpful...
