I'm not totally sure I'm following you, but from the sound of it: you have a form that lives on a landing page that isn't connected to a specific program or list. You do have a trigger campaign listening for submissions to that form, but when you submitted the form, then checked the results of that trigger campaign, you didn't see yourself in it.
To be sure it's set up correctly, you have the Fills Out Form trigger set with the appropriate form name, no filters, and the campaign is activated?
