Auto fill Fields, based on total amount of layouts and where layout tab is with in tab group

[chrisk3FHDQ]

So I am trying to set up a field to automatically count the amount of layout tabs are in the overall drawing set, and then have a separate field autofill with a number based on where a tab is with in the order.

ex: I have 10 tabs, the one field would autofill with 10, and would automatically change to 11, if I added another layout tab.
meanwhile a separate field is tracking where a certain layout resides with in that lot of 10, say I have layout tab 2, and I move it ahead of tab 4, then tab 3 is now tab 2, tab 4 is now 3, and tab 2 becomes 4, and the field number would auto adjust if layout tabs were inserted or deleted as well. 

I dont know if this is possible but it would save me some time if it was. any advice would be great. 

currently I am using the same field expression function to make changes across all layouts but I still have to go back in and change stuff manually as well

Are you wanting to fill out an attribute? I don't know of a way that auto updates but code for this is trivial.

There are also sheet set fields ( "%<\\AcSm Sheet.Number>%" ), but you'd still have to go and number within the sheet set.

Post a sample drawing.

I dont have fields but have update at any time.

The count of layouts 

(setq alllays (vla-get-Layouts (vla-get-activedocument (vlax-get-acad-object))))
(setq count (vla-get-count alllays))

taborder

(vlax-for lay alllays
(if (= numlay (vla-get-taborder lay))

maybe do a new list ((1 layout1)(2 Layout3)(3 layout2)....

I have do x of y for title block, it updates 2 attributes in the titleblock, which sounds like what you want again not fields.

Post a dwg must have title block with attributes.
