As shown in the error message, you have defined a callback (RING_callback) for the control but you haven't created it in the source code, so when the system loads the panel it warns you of that.

The solution is either to get rid of the callback editing the ring control or to create it by right-clicking on the control in the UIR editor and choosing Generate Control Callback from the context menu.

Pressing Ctrl+B on the control in the UIR editor will lead you to the control callback code, if it actually exists.
