Error regarding undefined parameters in TLC file

Hi while i am trying to deploy a simulink model into arduino mega 2560, these errors occurs. I am using matlab 2017b educationla version and the model contains matlab m s-function. last few months i was able to generate tlc file from this s-function (now no any more, i dont know why). I am using that generated tlc but i couldnt resolve the problem.
