I'm very familiar with Excel, but not very much with Word and its Merge fields.

I want to use a calculated value in several places, based on the contents of
merge fields. Example:

Subtotal: (Merge field A)
Tax: (Merge field B)
Shipping: (Merge field C)
TOTAL: (SUM of all 3 fields)

So, the question is whether I can have a cell where I can sum all 3 fields,
and whether I can reference that "TOTAL" field in another few places in the
document (rather than recalculating each time).

Thanks for any suggestions!
