imagine you have
column A yesterday's data
column B today's data
so you are trying to format the information in cells B2 to red if it is less
than the amount in cell A2.

Select cell B2.
Format Conditional Formatting

Formula is ... =B2<A2 (select the format with font as red)

Now all you have to do is select that cell B2, copy, then select the rest of
the cells in column B and do Edit Paste Special Formats.

I have rows of test results form specific products taken on different days, I
want to have a quick visual display of any downward trends and wanted to use
conditional formatting i.e. if cell is less than cell to left change font to
red, I can do this cell by cell but really want to do the whole worksheet in
one go or at least row by row
