Is the problem that the data is replaced or that it is replaced with a date of the incorrect format?
the problem is the data (words) are replaced with a date (just in the format xx/xx/xx) not left as is and just duplicated.
Have you checked the field for any auto-entered calculations or data look ups?
Both of those would be triggered when you duplicate a record.
Have you checked your layout to see if any layout object (such as //) or another field might be positioned on top of your text field?
will do. Thanks.
