>I have a simple form that is allowing a user to edit a record and I want to "revert" if they violate an index and throw an 1884 error. What is a simple way to do that or should I avoid the 1884 all together and only work with a memvar.
>Caveat, this is old code that we'll be replacing completely and I don't want to spend much time on it.

If you're using buffering, just do a tablerevert.
