DE2-115 Lab 1 Help

[Altera_Forum]

hi guys I just purchased the DE2-115 board and embarrassingly I have run into an error into the first lab itself: 

  We are supposed to implement a multiplexor so that the green LEDs mimic the input of either switches 0 - 7 or 8 - 15 based on the select input on switch 17. Heres my code; please tell me why only the x input is being passed perfectly to the green LEDs but when s is high only SW[8] is passed to the green LEDS from y inputs. Thanks!!!  :   Module TrialTwo (SW, LEDG, LEDR);     Input [17:0] SW;  Output [17:0] LEDR;  Output [7:0] LEDG;     Wire [7:0] x;   Wire [7:0] y;  Wire [7:0] m;   Wire s;    Assign x[7:0] = SW[7:0];  Assign x[7:0] = SW[15:8];   Assign s = SW[17];  Assign m = (~s&x) | (s&y);  Assign LEDG = m;  Assign LEDR = SW;     endmodule

I have changed it so that x and y are both being driven yet the problem persists. Additionally I tried to do the 4th part of the same lab and no matter what inputs I give the 7-seg display shows all segments high. This problem persisted even after i changed the code so that the display should show six whatever the input. Is it possible I need to delete the old .sof file before recompiling or something? Heres my code, please help!:

as you can see in the above assignments to the Ini elements I muted the original code and replaced it with code to display the number 6 on the 7-seg but still no change
