I'm working on excel 2003, and I have a list table that has six columns.
Column E contains volatile data which computes the number of days the row
item has been on the table until the entry is updated again.

What I've been trying to do is to shade the cell in column A, depending on
the value in the corresponding cell in column E which falls along the same
row. The only method I've been able to figure out so far that is guaranteed
to work is to make conditional formats for every cell in column A, but that
will be too tedious, and also inappropriate, since the data occasionally gets
rearranged because it is frequently updated, thus it would change the cell
references.

Example:

A | B | C | D | E
| | | | 18
| | | | 7
| | | | 24
| | | | 2

condition 1: E 20 Red
condition 2: E 13 Orange
condition 3: E 6 Green

I think i need a formula to make the conditional format refer _implicitly_
to the corresponding cell that is along the same row under column E, but i
just can't figure it out. Hope you guys can help me out with this. Thanks!
