Modify array formula returning value associated with minimum price calculation

I have an array formula, which I do not understand enough to modify in column J of worksheet “Item_data”.

=IF(VLOOKUP(ItemTable[[#This Row],[PPT]],PriceTypeTable,3,FALSE)>0,LOOKUP(1,1/FREQUENCY(-9^9, IF((Basis="C")*(PriceType=ItemTable[[#This Row],[PPT]]),Multiplier,9^9)), CustPrcType),"")

The formula returns the first value of the Customer Type associated with the minimum customer price from Column G in worksheet “Type4_data”.

The requirement is now to return the first value of the Customer Type associated with the maximum customer price from Column G in worksheet “Type4_data”.

Could someone provide me with the correct syntax and explain?
