No, 2003 is limited to 3 conditions (giving 4 possible formats: default + 3).
You can do it in VBA, you use the worksheet's _Change() event to detect a
change in the cell(s) and generally use a Select Case statement to evaluate
the value of the cell, setting any number of formats based on those results.
Any code would go into the worksheet event module (right-click the sheet's
name tab and choose [View Code] from the list to get to the proper place).
You can record macros while setting up formats such as you want to get the
syntax needed to set up a particular format scenario to use within the
various Case Is portions of the Select Case block.
General code stub for a test, with several possible tests to see if the
change took place where you need to know. You can combine up tests to see if
it is in just about any kind of are you need to test.
