I have a field for quantity in an hl7 message that I want to use the math function multiplication on to multiply the field by two. I do not know how to use this. I have put the field 0(0).FT1(0).00364.[0]*2 and have also tried 0(0).FT1(0).00364.[0]*(2) but it still is keeping the original quantity. Is there a specific nomenclature or format for indicating what you want the specific field multiplied by? 😥
