This form displays all of the indicated column, and subscripted portion of it, in different fields. You can display different, subscripted parts of a column in different fields, but the parts cannot overlap. That is, portions of a column cannot be displayed twice on the same screen. Review all uses of the indicated column. Perhaps you did not intend to name it in both places. Perhaps two or more columns of the same name exist in different tables, and you need to use the table name to distinguish them. Otherwise, use nonoverlapping subscripts on each field of the column.
