Node not found in Simulink

I tried to build a circuit on Simulik using the vr sink but I got an error.

Error reported by S-function 'vrsfunc' in 'vrsink_circuit/VR Sink':
Node 'finger_1' not found.                        

What does it mean? The error belong to the original model that is inserted in vrsink or the connection of vrsink in the circuit itself?

Please provide the model, so that a workaround may be provided.
