I have a merge letter using multiple IF and IncludeText statements to vary
the text of the letter. This works correctly for all of the various IF
statements when I merge the letter.

However, I also have a "master" document that I am using for 2 reasons:
1) to merge multiple forms (letter, envelope, information forms, etc)
including the above letter in one pass (they all use the same data source),
and
2) so that I can vary the font size of the letter based on criteria in
the datasource. This is accomplished with the following:
{IF {MERGEFIELD Require_Large_print } = "True" "{INCLUDETEXT
"AckLetterRecpt" \*CharFORMAT}" "{INCLUDETEXT "AckLetterRecpt" \*
CHARFORMAT}"} (the first/true part of the evaluation is formatted to a
larger font size)

When I merge the master document to a file, everything looks fine. However,
when I *print* the document on paper, a number prints as part of the text
where the result of an IF statement appears. The number is either 1 or 2,
which appears to depend on the evaluation of the Large print field that is
made in the master document. The number is not visible or selectable on
screen in the merged document, and does *not* print if I merge directly from
the merge letter -- only if I merge from the master document. The IF
statement where this appears is:
{IF MERGEFIELD VIP = "True" "

" "signature"}
(the actual letter has the location of a file containing a graphic with the
signature instead of the word signature, but I changed it to text for testing
purposes).

The 1 or 2 overprints the letter "s" in the word signature.

I am completely stumped as to where this number is coming from, why it is
printing in this case (and not from any other IF statements) and how to get
rid of it.

Any help or suggestions for what to look at would be greatly appreciated.
