You can do this type of simply dependency check right now. However, you're correct that right more complex dependencies could be easier. >The "and" and "or" method also is useful for dependences between fields. The biggest issue w/dependencies is circular logic--the library has to take in account logic that ends up looping. In my qForms API, I had a createDependencyTo() method to handle this. It allows you to write really complex dependencies between fields. -Dan
