the 'Controlled Current Source' block cannot be left open-circuit because it is modeled as a current source

Dear,

I want to ask one question about "controller current source". When I run the model.the error happened --

"the 'Controlled Current Source' block cannot be left open-circuit because it is modeled as a current source.You should try to resolve the open-circuit topology or delete this block from your model.". The model picture and error picture can be seen in the attachments.

How can i resolve this question? Thank you very much.
