One of the tokens for the 2d dimensions is wrong. It appears to be a face frame vs not issue again, us face frame users usually measure from the face frame overall size because applied ends would sit behind. And in this particular unit i do have a applied end, but the cabinet is 941, not 932. 932mm is the cabinet with the applied end taken off.. 

and why its taking the overall width from the left end dimension when its also a right applied end, and also overall width so neither left or right...? i'm not sure but it appears to be.

=Width-IFERROR(IF(L!Right_Applied_End=1,Applied_End_Thickness_Right,0),0)
