I am trying to simulate a full state feedback on Simulink, the problem is showing question marks at each connections, I watched several videos on youtube how to configure but can't see similar to mine. Please could someone advice which configuration should I do to remove the the said questions marks? please see attached simulink file. please change file extenstion from .txt to .slx becuase I can't upload the file.

Thankyou in advanced for your kind attention.
