i am trying to CONDITIONAL FORMAT RANGE OF CELLS BASED ON ANOTHER RANGE OF CELLS I.E IF THEY MATCH (CELL FOR CELL) no format if one cell different to its counterpart formatting applied

I have achieved this in office 2007's excel which works as i want however the pc this program is destined for runs on excel 2003 so the conditional formatting doesn't work

so im looking to create vba code for it but cant get my head around converting the working formula into code

NOT (E8:R31=E54:R77) SETS OFF A CELL FILL

thanks in advance to anyone who can help out
