Output to RTF leaves totals at zero

Odd problem with a report outputting to rtf. The report footer has
some VB code that totals up various values and places them in unbound
text boxes.

However, when I output to RTF via docmd.outputto the totals are
shown as zeroes. The print correctly on the report and also show
correctly when outputting to html or text, but not in RTF?

So I guess my question is WTF is up with RTF!
