I would like assistance with some conditional formatting.

What I would like to achieve is to highlight a cell dependant on a set criteria.

As you can see from the attached I would like to highlight the highest value in column H based on the Load Group selection (column D)

For example.... I would like the cell that contains the value of "32" to be highlighted as the highest value for Load Group "D. Motors"

Thanks in advance.
