block with attributes

Is it possible to enter new text with attributes in block that is already defined? In acad 2006 in block editor when i do that and put block in drawing, it shows only attributed text that was created when block was made first time. Is that normal or am i doing something wrong?

If the attribute mode is "fixed" it cannot be changed, otherwise ATTEDIT will alter attribute values one at a time. There are also routines to manipulate block attribute en mass or globally. You need to ask more specific questions.
