fix and successfully submit my web app to facebook

i want someone to fix (if needed-i assume i am just doing something wrong) and submit my webapp to facebook with the right facebook permition. At the beggining everything was accepted but when i try to use the webapp, i get a message #error230 Requires pages_messging permition to manage the object-see attachment. When i resubmitted to facebook asking for this permition, theit tester checks the facebook pages bot-that doesn't do anything- instead of testing the webapp. i will pay only when app is approved.
