There is nothing that you can do as part of the built-in mail merge
functionality that can take care of that situation. However, it would be
possible to create a macro that compared the mergefields in the mail merge
main document with those in the data source and take some action in the case
of those that do not exist in the data source. Determining what that action
should be is something to which you would need to give a bit of thought
however, as just deleting (aka ignoring) the mergefield in the document, may
result in a sentence or paragraph appearing out of context or not making
sense.

Hi, I work at a charity, and we have a template letter document that
prints
different receipt letters depending on different donations.

Sometimes, raffle tickets will have been purchased, and we need to add the
ticket range info to the letter. The problem is that letters without
raffle
ticket information don't have ticket info fields in the data. Therefore,
I
get "Error! MergeField was not found in header record of data source"
errors.
Is there a way to display field data only if the field actually exists in
the data source? Something like 'if exists {mergefield firstTicket}' or
'{if
{mergefield firstTicket } is not null'

thanks for any help
