I am using FileMaker 10.3, with Mac Pages as the word processing program.
I have been doing this for several years, and today have had a problem for the first time.
I maintain a bibliography database with author, year, article, source etc. I wanted to add some additional references. I created a word-processing, tab-separated text of the new entries, which FileMaker identified as a tab-separated text. When I attempted to import it, it only imported the first field.
I created a clone of the existing database, and imported these same records into the clone, and it created the records just fine.
When I tried to import the clone into the main database, again, only the first filed appeared in the main database.
