Thank you for your post.
Although it has been several years since I used Microsoft Word, I recall exporting data from FileMaker Pro using the "Merge" option. This created a Microsoft Word Data Merge document that was used with the main document for mail merge. That is, in FileMaker Pro, pull down the File menu and select "Export Records..." For "Type", select "Merge".
Can anyone else confirm if this is the correct method?
In Word (2004), activate the data merge manager (tools) and identidy your (merge) document.
Then identify the data file and select any filemaker pro database - except I just found out that .fp7 files are not selectable - .fp5 files are....
Then you can insert the file-labels in your document as appropriate, and finally carry out the merge.
