IF Statement with multiple conditions

[Chants89]

Please can someone help me with this IF statement and let me know what I am doing wrong:

IF(AND(SUM('Values'[Values])<=SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*4),SUM('Values'[Values])>=SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*0.75),2,

IF((SUM('Values'[Values])<SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*4),1,

IF(SUM('Values'[Values])>SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*0.75),3,0)))))

I keep on getting the following error:

Too many arguments were passed to the SUMX function. The maximum argument count for the function is 2.

@Chants89 , The first filter end here

FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*4)

Then there is comparison , the sumx never end

SUM('Values'[Values])>=SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*0.75),2,
IF((SUM('Values'[Values])<SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*4),1,
IF(SUM('Values'[Values])>SUMX(FILTER(JoinedExtractData,JoinedExtractData[measure var _last6]*0.75),3,0)))))

please write them in var and the try to club later

Us Switch with true option if needed
