All, I've been trying to create a base class with 2 properties and a sub class based off of that with 5 of its own properties and the 2 derived by the base class. I'm having lots of problems. I placed an example up and some1 said that I was using code froma beta testing version. I've looked @ the examples in the help for SP3 but I'm a little confused because I don't see a big difference in what I posted and the example. I've seen a few examples that haven't helped clear it up because they don't have properties. I'm confused any help? Ryan
