Block the entire range you want to format conditionally - in your example's
case, A1:D2

Click on Formatting, select Conditional Formatting, and in the window that
then pops up, change Cell Value Is to Formula Is. In the box to the right of
this type
=$A1=$E1. Click on the format button, select Patterns, select Red, and OK out

Hi,

I've looked through the conditional formatting section but can't find
anything.

Here is my problem...

A B C D E
1 DD SS WW 1
2 SS QQ EE 4

Now what I require is for section A1-D1 to highlight in red when A1=E1, so
for my example I would only expect to see one row highlighted because there
is only one match.

Your help again is much appreciated.

Regards,
James.
