if retail90_30 = 'Retail 30'and Type = 'Brand' then Ingrediant_Cost = Pre_AWP*(1-(&Retail_30_B.));
else if retail90_30 = 'Retail 30' and type = 'Generic' and MAC = . then Ingrediant_Cost = Pre_AWP*(1-(&Retail_30_G.));
else if type = 'Generic' and MAC <> . then Ingrediant_Cost = MAC;
else if retail90_30 = 'Retail 90'and Type = 'Brand' then Ingrediant_Cost = Pre_AWP*(1-(&Retail_90_B.));
else if retail90_30 = 'Retail 90' and type = 'Generic' and MAC = . then Ingrediant_Cost = Pre_AWP*(1-(&Retail_90_G.));
else specialty_ind = 'Y' then Ingrediant_Cost = Pre_AWP*(1-(&Specialty_Disc).);
Final_ING_Cost = min(U_and_C, Ingrediant_Costpe);
run;

Can some one please help me why am I getting the error? Is there any issues in the macro?
