Am using the following script in an expression which is returning values as based on the conditions:-
=sum(if((year(enquiry_award_loss_date)=YR and month(enquiry_award_loss_date)=Mth and (TeamStatus = 'Active') and (opheadm.status<9)and (Whiteboardexclusion<>'1'), if((opdetm.spare)>'0',opdetm.val/opdetm.spare,opdetm.val)))
This works however, I need to add another calculation changing the opdetm.val returned to a negative if the following field:- opheadm.Order_No like 'CN%' .
if(Wildmatch(opheadm.Order_No,'CN?') so here it will be true only if there are three letters like CNA or CNS. But if there are more letters like ACNbi or CNlio then it will always fail. For those you can use '*cn*'
