Language OptionsCustomize Regional Options so the the separators match
those used in the data source.

I'm Creating a Mail Merge document, where the data source uses the latin
america decimal notation "," for decimals "." for thousands separator. All
the calulations on the docuemt such as {= ( {MERGEFIELD Edad} * 2) } get
an
error : !Invalid Character Setting. Does Mail Merge Support this notation
?
If is switched to standard notation "." for decimals, "," for thousands it
works.
