Why are you using a macro to update the fields, rather than just using their 'Calculate on Exit' property? As for selectively updating, that's only reliable if the fields concerned don't have any dependencies on other fields in the document, since other events, such as printing or previewing the document can also trigger updates.

I know that I can update/calculate all FormFields at once but in this case I have dependencies between fields and some of them can't be updated. (Field with amount can't be updated after writing in it number because than field with amount in words will broke).
So I need macro that will update specific field or will update all but one or two. Do you know one?
