I Cant Figure Out Midi

Hey folks. I just cant figure out how to configure the midi controller. I see from the logs, that i am sending the midi and waves sees it. But i am struggling to fill in the values in the controller.

Say i want to open a snapshot with an external id of “0009”. I understand the midi controller to be one. But just now clue what to pick and what value to put in. If i try to enter a snapshot # in the data entry box, it says i cant enter data in the text box. Can anyone load a screen shot for me?
