Ricki,

After conferring with some associates who are more knowledgeable on
international issues, it appears that you can use Control
PanelRegional and Language Settings to set the number and currency
separator to a space and the formfield and calculation field will work.
I just confirmed this in Word2000 but didn't get it to work initially
with Word2003 at home before I left for work. Of course the user would
have to set his/her settings to match. If what you have is working it
may be better to leave as is.
