Calculating absolute values from cumulative data set

[Cunners123]

Hi,

I am trying to calculate the absolute month values (in month difference) from a cumulative data set.  Where am I going wrong with the formular?

thanks

Thanks  @ryan_mayu . That has worked but I realised  I left a fundamental part out. I will have different sites so want to apply this calculation per site i.e so I get the january absolute value for site 1 and site 2 (i will have lots of sites in reality) is there a quick edit to account for this?

Using current formula it goes a bit wrong

Thanks for your help

@Cunners123 

pls try this

Column = 'Table'[cumulative]-maxx(FILTER('Table','Table'[Month]=EDATE(EARLIER('Table'[Month]),-1)&&'Table'[site]=EARLIER('Table'[site])),'Table'[cumulative])
