If the data field is called 'andorrapercent'
then the construction would be:
{={Mergefield andorrapercent} * 100 \# "0%"}
Note that you need to enter this manually using CTRL+F9 to set each pair of
field boundaries - see http://www.gmayor.com/formatting_word_fields.htm
which I updated as a result of your question.

I am still trying to resolve this, but I get the error
message "!santex error, andorrape" I am using Word 2000
(I don't know if this makes a difference)
Thanks

I have now figured it out, blame it on a long day at
work. Thank you VERY much,
