Using Ajax output to leverage panel visibility on a form

All,

On a form, I am trying to leverage panel visibility (or any variable for that matter), using the current state of an Ajax component. Trouble is, there doesn't seem to be any output variable for the Ajax component. The Ajax model will currently state Not Started", "Started" or "Completed" states. I would like to change the current view for the end customer based on this output. Please advise if this would be possible, or if there are other similar approaches that may satisfy. Ajax model screenshot attached.

Thanks!!
