Fields Referencing Same Block

[Michael.BrubakerR9GDT]

Hello all, I am relatively new to AutoCAD. I'm sure this has been asked in numerous different ways but I can't seem to find the answer I am looking for. I might not be wording what I'm looking for clearly in my searches. 

Attached is a sample block that when inserted ask the user for specific information. I want the fields inside the block to update accordingly.

0s there a way to do this that isn't convoluted or has my users exploding the block? I will be doing this for numerous blocks to make editing these types of drawing super simple for my users.

Any help would be greatly appreciated.

EDIT: These blocks will be reused multiple times with different values in the same drawing so I cannot have a nested block with the outermost being the fields updated on the innermost block.

@Libbya - Oh sheesh, sorry about that. This is killin me. The Blocks on the sides and top of the viewports work, but the inserted one (same block) won't update properly. I don't know how this is even possible. But then I tried using MTEXT in the callouts, and put an attribute for it to reference on defpoints. I want the attribute to be invisible, but just put it on defpoints so you could see it. at 1st glance.

@Libbya Good to know, I totally understand that. I was just making sure.

@Libbya  - Nevermind, I figured it out. Just FYI: you only get the "Display value for block reference" checkbox when you first make the attribute definition (ATTDEF).
