The tag code is c09==0 && Code009==0 and it works, it means the statement is true. How to add a second code009f in, a either/or situation. As long as there is a code in one of the two positions then the statement will be true.
Use the || operator for or logic. I would be weary of putting too complex a logic operator in for the simple fact that it can be difficult to understand by a third party. I would recommend making a program using nested if else statements. You can comment the program easily and call the program in the general binding of the tag.
