Hi, hope you can give me some suggestions why my calculation doesn't work. 
I want to subtract an area between 2 injections.

Diff_Area=U%.%..CCompRef1[Area]-A1.1..CCompRef[Area]

CCompRef: peak name was entered in the processing method.
Thanks in advance!!

    Is the formula written correctly? The syntax should contain parentheses around your argument, plus you have too many periods in that formula. Only two are required if no intersample functions like Average etc are used. Plus you dont need to specify the label for the Unknown samples, that way the formula will work for all the relevant samples. Change the formula to:

    ABS(CCompRef1[Area])-A1.1.(CCompRef1[Area]))

    The ABS is short for Absolute to return a positive number in instances where the sample area of CCompRef1 in your unknowns is lower than that of A1.1.(Area).
