If C is a calculation form field and both A and B have "Calculate on exit"
set, C should update automatically.

I am trying to find a way to allow Word users to enter data into a table
and
have simple calculations automatically update.

The document is a protected form that allows users to input measurements
into columns A and B, and ideally Column C should automatically calculate
the
sum of A and B. However, Word requires you to tab to the field and press
F9
to get the result; since my form is protected they can't tab to that
field.

I tried setting it up in Excel and embedding the table, but Excel won't
let
me format cells as form fields that users can enter data into.

Any help would be greatly appreciated.

Thanks!
