Fortran Error:Bad continuation line at (1) - unix

Question

I am trying to use fortran to write a Unix script into a file. Nonetheless, it keeps reminding me that my format is incorrect. I have been doing this for many times and they are all succeed to be compiled. For this time, I do not know what goes wrong. I have attached my codes and the information on errors and I will be very grateful if someone can point out my mistakes. Thanks!!!
