Mail merge, text changes

[Dan]

I am trying to create certificates that I have made. I have four different
fields that I merge into it. I have done this before with no problem. But
now, when I select preview publication, everything looks good, when I am done
I select "create a new publication" and when the new publication comes up the
font in which the merged fields are in (not just the merged part of it, but
all the text surrounding the merged parts) changes from Perpetua, which is
what I want it to be, to Times New Roman. Does anyone have any ideas?

I appreciate the help!
