    Most HDL programmers would use a behavioral description for the shift register. if you're required to use a structural description with individual FFs, sketch a logic diagram on a piece of paper first. Besides the points already mentioned, you didn't connect a clock to the DFF. Not surprizing, the code does nothing.
