I'm new to facebook app development and i cant seem to figure this out. I have a simple app i made (an iframe website) that i want to add to a tab on my facebook page. When i try to click on the + tab to add it to my page i only have a few options of youtube, events, fbml... When i do a search absolutely nothing comes up unless i search for those items i just mentioned before (youtube, events, fbml).
Type this into your browser's url bar with the appropiate ids. (I already assume you have configured the app settings for page tab urls,etc).
