I think I got past all the warning messages except this one:  

"You have chosen to open a file that may contain viruses or be
otherwise harmful to your computer.  It is important to be certain
that the file comes from a trustworthy source.  Do you want to
continue?"

This message is displayed when a person tries to open a document (e.g.
an Excel document) that is attached to an Infopath form (file was
attached with the file attachment control).  Is there a way to avoid
this error?

Thanks,
Carol
