Merge Field Results

[beth_83]

Is there a way to store Merge field results as hidden and display only when necessary?

i.e. show the fax number if the letter is being sent by fax or show the email address when sent by email?

At the moment Word won't put the merge results into the document if they are hidden so i have to merge with them showing then click a button to hide / show as necessary.

Is it possible to import merge data somewhere hidden for access later through a macro if necessary??

Thanks
Beth
