Need help to implement ESTBeacon

I have followed this tutorial
and have problem on this:

// calculate and set new y position
float newYPos = self.dotMinPos + ((float)closestBeacon.ibeacon.rssi / -100.) * self.dotRange; = CGPointMake(self.view.bounds.size.width / 2, newYPos);

the IDE says 'Property 'beacon' not found on object of type 'ESTBeacon''

How to fix this? I'm newbie.

Hey there, that's a "bug" in the tutorial (:

Instead of "closestBeacon.ibeacon.rssi" it should be simply "closestBeacon.rssi".

Sorry for that, we'll get this fixed!
