Cells A$1$:A$10$ contain a set of numbers. You want to select those cells that contain numbers less than $100$ and highlight those cells in red, and you want to do it in such a way that even if some numbers change, those cells still get highlighted in red if their value falls below $100$; otherwise, the cells should not be colored.
