Hello @Oussama_Baklouti ,

The modelListener seems to be included in all 4 of your screens.
But you have a function called "Receive_SOC" in the modelListener.
I think that simply declaring that function in screen 1 to 3 (like you did in screen 4) would solve the error.

I hope this helps.:smiling_face_with_smiling_eyes:
