Probably the easiest way is to use conditional formatting. After selecting
the cell you want to format, the Click on Format, Conditional format and
enter the values that will control the display in that cell.

For instance, if I want cell A2 to turn Red with a Bolded integer greater
than 0 and less than 10, I would choose "Cell value is" "between" "0 and 10",
then click on the format button and choose "Red" font with "Bold". If you
want a border around the cell you can choose that then too. Hope this helps.

use VLOOKUP to populate the slave sheet.
