Import records is a nice, but limited new feature added to FileMaker 11.
To get what you need, you'll need to use the original, non-recurring Import Records action. Once you can get the results you want manually, you can set up a script so that you can do this with the click of a button. Import records gives you many options--including whether the import adds new records or updates existing records--so you'll need to look this feature up in FileMaker help and figure out which options produce what you need here. Since this action has the potential to add or modify a large number of records, make a back up copy first so that you can toss the file and start over if your import doesn't produce the results you expected.
Thanks for your help. Import records works much better. Appreciate your help.
