The MAX function only accepts a column reference as an argument

Hi Everyone

I have a column in a table Data[MANAGEMENT_PT] and I am trying to grab the max value for that then apply some conditions in DAX to return some values. When I put in my code however I keep getting the following error:

The MAX function only accepts a column reference as an argument.

HRI = if (MAX(Data[MANAGEMENT_PT])=0,1,
(if (MAX(Data[MANAGEMENT_PT]=1) || MAX(Data[MANAGEMENT_PT]=2),2,
(if (MAX(Data[MANAGEMENT_PT]=3) || MAX(Data[MANAGEMENT_PT]=4),3,
(if (MAX(Data[MANAGEMENT_PT]=5) || MAX(Data[MANAGEMENT_PT]=6),4,
(if (MAX(Data[MANAGEMENT_PT]=7) || MAX(Data[MANAGEMENT_PT]=8),5,
(if (MAX(Data[MANAGEMENT_PT]=9) || MAX(Data[MANAGEMENT_PT]=10),6,
(if (MAX(Data[MANAGEMENT_PT]>=11) && MAX(Data[MANAGEMENT_PT]<=13),7,
(if (MAX(Data[MANAGEMENT_PT]>=14) && MAX(Data[MANAGEMENT_PT]<=16),8,
(if (MAX(Data[MANAGEMENT_PT]>=17) && MAX(Data[MANAGEMENT_PT]<=19),9,
(if (MAX(Data[MANAGEMENT_PT]>=20),9,0)))))))))))))))))))

Does anyone know what is wrong with my formula?

Thanks in advance
