The functionality you seek is built into Word itself. And, as I clearly said:In a document with 'filling in forms' protection applied - which is required when using formfields - what you describe simply isn't possible unless one breaks the document into Sections and leaves Section containing the formula fields unprotected. In Sections of a document with 'filling in forms' protection applied, only the form fields (not any formula fields or other fields) are accessible for selection or user input.

For a fairly simple demonstration of formfields in action, see: https://www.msofficeforums.com/171152-post2.html

I'm a bit confused between field codes {F9, a-F9, & c-F9} and field controls.

I've tried field code several times and rarely get them to work. I tried to calculate the end of the loan term by using the VBA function DateAdd("M", StartDate, nper), where StartDate and nper are numeric Text Form Fields. Can field codes reference these? I tried something like:
{ =DATAADD("m", {REF StartDate }, {REF nper} ) \@ "MM/dd/yyyy" }

But get
!Syntax Error, (

Sooo, instead I did everthing with Legacy Text Form Fields and the Exit field.
What I was initially asking, is there a way in the exit sub to tell if the formfield was actually changed?

My hack was to create Static variables then compare that static var value to the formfield value:
ActiveDocument.FormFields("StartDate").Result
if different, I update other FormFields, then before leaving, copy the current formfield value into the static variable.

This is mostly working but somewhere the static vars are re-initialized (Using the debug.print command)

(My previous message was trying to use field codes instead of formfields exit sub
