Need Help using References in MText in Block

[PFHeller]

Our jobs frequently have dozens of sheets. Each sheet has its own sheet notes that are numbered. In any job...there are usually three or four sets of notes. Some sheets may get set #1, others set #2....and some may get a combination like #1 and #2.

Goals:

• Keep these as either blocks, or xrefs, that way any changes to the sets of notes only have to be done once and they will adjust on every sheet they've been inserted too.
• Try to have them all in one dynamic block with visibility options, that way you don't have to BEDIT very many times to update notes.

So i've created a dynamic block that works great....I am almost where I need to be. But one thing is eluding me. The numbering of the notes.

I made Visibility states so you can see set #1, or set #2, or see them both together. Now if you see them both together you have to move one down so it follows the other one.....easy to do with a linear move. However, the numbering is off. If I have a sheet where it only shows set #2....then it needs to start numbering at 1. However, if I have a sheet where both sets #1 and #2 are showing....then I move set #2 down and now the numbering needs to start where set #1 left off. And there is the rub.

Here's what I tried:

I tried creating a User Variable in the block where you could pick what number the set would start at....however, only Attributes can reference items within the block. But if I use an attribute, then it won't update for all blocks when I update the parent definition. I thought of using a "constant" attribute...but this doesn't work because then the field won't update since it is "constant".

I'm all out of ideas and i'm hoping that you brilliant people can help. Any ideas?
