Word replaces formula fields instead of creating new ones

[dani.ahrens]

I quite often use several formula fields in Word, to do small
calculations (eg to work out VAT on an order, calculate how much
remains in a particular budget).

Since upgrading to Word 2003, I have found that when I try to add a new
formula field to a document that already contains one, Word assumes I
want to edit the field that is already there, and amends the old
formula instead of adding a new one.

Does anyone know how I can stop this happening?

Thanks,

Dani
