Thanks Martin
Putting the call into the Load method worked just fine. I thought the Init method fired before the Load method, but I guess not.
I built the Alter Table function for the situation where you have an existing system distributed to many clients and you need to add (or alter) one or more fields in a table for a new release. The only alternetives are to buy expensive 3rd party software or build a conversion utility program for the client to run before installing the new version.
Any thoughts are welcome.
