An additional item on this. I have noticed that after the table import, some of the more complex auto-enter formulas are blank after the import. The value for type of calculation, indexed, replace are all correct, but the formula itself is missing.
Thank you for your posts.
If FileMaker Pro cannot determine the table name and field name, then calculations will display as <unknown>. In the case of auto-enter formulas, it will be left blank so as to not cause errors when adding records.
