Make a copy of your SCT & SCX files that you want to modify.

USE FILE.SCX

brow for "ControlSource" $ Properties

This will give you only those records that have a controlSource.

You can then go through each record and change the ControlSource from the m. to the oTable1. pretty easily.

If you have a lot of forms you could probably write some code to go through each and change it for you.
