Amazing! Method will toute itself as being customizable, but then it's so difficult to customize I can't even do something basic like add one field . . . and so I need to pay for more consulting! This reminds me of the days of DOS on PC's. Sure, you can customize your computer if you memorized a bunch of crazy commands.
Instead, you should be offering step by step instructions, like most applications provide, that shows me how to do this. For example, I don't know what options you chose when you setup your filter.
