Mission:

Trying to have cells under column A turn red if the adjacent B cell is
empty, and is 15 days overdue.


Attempt:

Conditional formatting =A1+15<=NOW() [Red Font]
Conditional formatting =A1<B1 [Default Font]

Success!!

Problem:

I want to do the same thing with A2 to B2 A3 to B3 etc....However if I
highlight lets say the entire column, the entire column ill be dependent on
that one cell. I need a way to do this so that each cell react to the cell to
the right just like I did in my example above.
