unable to create symbol file for current file (Verilog HDL file) in Quartus IIweb13.1

Hi Tricky,

I am trying to run 'My_first_fpga' tutorial on my cyclone III starter board, verilog code is as below:

// This is an example of a simple 32 bit up-counter called simple_counter.v

// It has a single clock input and a 32-bit output port

module simple_counter (input clock , output reg [31:0] counter_out);

always @ (posedge clock)// on positive clock edge

begin

counter_out <=# 1 counter_out + 1;// increment counter

end

endmodule// end of module counter
