Hi Paul, probable the Data Environment is overwritten your settings for the buffering, if you suspend the execution when you get the error and check the buffering of "Department" I think you will see it does not have Buffering 4, if you don't want to use the Data Evironment then assign your
Buffering in the Init event of the form.

Good luck.
