Computed Code Close window button

The computed code sets the variable X, and makes use of the X(order#) array. In this case X(1) refers to the EMAIL NAME, the cross-reference value we defined with order number 1, and X(2) refers to EMAIL ADDRESS, the cross-reference value we defined with order number 2. Our computed expression sets X to email_name@email_domain, and converts the result to uppercase. This will be our third cross-reference value (order number 3), which will be subscript 1 (the only data subscript) in our index.
