>Custom is not able to be put in a form directly. You need to first define a class based on teh custom base class and then you can put that class in your forms.

Thanks. I was beginning to suspect that. I'm not sure why this limitation, since you can do it in code with ADD OBJECT .. AS CUSTOM. But anyway, it's no big deal to do it the way you suggest. I just thought I was missing something obvious.
