I am having a issue with a formula when trying to subtract a value from another in the formula it is subtracting the wrong amounts =IF(($A17-SUM($D17:J17))>0,IF((K$14-SUM(K$15:K16))<=($A17-SUM($D17:J17)),K$14-SUM(K$15:K16),(K$14-SUM(K$15:K16))-($A17-SUM($D17:J17))),0)

Below is the formula I am working with =IF(SUM(C44:I45)>=40,SUM(C44:I44)-8,0)+IF(SUM(J44:P45)>=40,SUM(J44:P44)-8,0)+IF(SUM(Q44:V45,X44:X45)>40,SUM(Q44:V44,X44)-8,0) However, I'm not get the correct outcome. It is not considering if row 45 is less than 32.
