I have made a block with 3 attributes. The content of all 3 is always equal, but different between each individual instance of the block. So I wonder if it is possible to make connections between those 3 attributes, that when I Edit Attribute #1; Attributes #2 & #3 update automagically. (pun intended) I do not need to write same content 3 times? Is that possible? Thanks for all answers. I have AutoCad LT 2011 on windows XP Pro SP3  32bit.  I've tried using field, object then selecting the att I want as my master attribute then selecting value, but doing this only puts the default from the master block in the value of the attribute I want updated.
