There are a couple of different ways you can do this. You can either make a custom refraction map which is almost completely white where the glass is and then black where your "sticker" will be. The other option is to use a VRay blend material where you make a custom mask map (to be used in the mix slot) that's totally white where your "sticker" is and totally black where your glass is. You then make a glass material as the base material and your "sticker" material as a coat material that uses the mask map to control its opacity.

As erick said, the most practical solution is probably the blend material...the thing that you probably forgot to do was the black and white opacity mask for the sticker material
