Conditional Formating of "grouped" rows Pivot Table on other cell value criteria

I'm trying to highlight my Pivot Table data, with grouped values, based on input from another cell.

In Pivot Table, Column A has grouped values from 0-300 in ranges of 25 increments.

0-25
25-50
50-75
75-100
100-125
etc.

I'd like to use input from a different field, to highlight all rows of data that has a grouped value higher than my input field. So if input is 40, all rows above 25-50 should be highlighted.

If input is in "N2", I'd like all rows in pivot table that has a grouped value higher than "N2" to be highlighted and this is causing me headaches and frustration :-)
