Using Custom Property Driving Rotation

While I learnt how to use Drivers in Blender. FINALLY!

I could not use Custom Property of an object to drive a Bone Rotation.
Is there something I did wrong?

Drivers Blend.blend (637.8 KB)

Err Guys I managed to figure it out. Can the forum mods or… admins delete this topic?

You should tell here how you solved your issue, so that whoever searches for same thing can benefit.

Ok for starters I should have linked the drivers directly to the Custom properties. I didn’t do that when I started this thread.
