Conditional formatting for different answers?

[Bal_Ocado]

Hey Guys,

I've got a pivot table infront of me and just wondering if this is possible. Pivot table columns go as:

Mechanic - Brand - Pack - Account

I need all of these as they are. The next column is months.

After this I have financials. I want to create a conditional format where financials are highlighted if the same Mechanic - Brand - Pack - Account combo has differences in financials by month.

Is this possible??
