>I have all of those things done, and I'm still getting the "No update tables..." error??? This is driving me nuts because I've done this before and everything worked fine.

Have you checked to see if all the data is updated during your Transaction?

Also, are you using Row or Table buffering? If Table buffering, check your parameters in the TableUpdate() command. TableUpdate(.T.) is VFP3 syntax, and VFP5 offers other options.
