Verilog: Converted Integer Not Working for For loop - for-loop

Question

I am writing a program in Verilog that accepts a binary value, converts it to Integer, and then prints "Hello, World!" that amount of times.
However, whenever I run the program, there is no display of Hello, World. Here is the code:
// Internal Variable
wire [0:4] two_times_rotate;
// Multiply the rotate_imm by two (left shift)
assign {two_times_rotate} = rotate_imm << 1;
integer i, times_rotated;
// Convert two_times_rotate into an integer
always #( two_times_rotate )
begin
times_rotated = two_times_rotate;
end
initial
begin
for (i = 0; i < times_rotated; i = i + 1)
begin
$display("Hello, World");
end
end
assign {out} = in;
endmodule
I tried using the following for loop instead:
for (i = 0; i < 7; i = i + 1)
And this one prints Hello, World seven times, like it should.
*UPDATE*
This is what I have in my code so far. I am trying to do a for that compares bits instead. It is still not working. How do I fully convert from binary to integer in a way that I can use it in the comparison in the for loop?
module immShifter(input[0:31] in, input[0:3] rotate_imm,
output[0:31] out);
// Internal Variable
wire [0:4] two_times_rotate;
reg [0:4] i;
// Multiply the rotate_imm by two (left shift)
assign {two_times_rotate} = rotate_imm << 1;
integer times_rotated, for_var;
// Convert two_times_rotate into an integer
always #( two_times_rotate )
begin
assign{times_rotated} = two_times_rotate;
end
initial
begin
assign{i} = 5'b00000;
assign{for_var} = times_rotated;
for (i = 5'b00000; i < times_rotated; i = i + 5'b00001)
begin
$display("Hello, World");
end
end
assign {out} = in;
endmodule

times_rotated is 32'bX at time 0 when the for-loop is being evaluated. The for-loop is checking i < 32'bX, which is false.
Based on your update, this may be what you are intending:
module immShifter( input [31:0] in, input [3:0] rotate_imm, output [31:0] out );
integer i, times_rotated;
always #*
begin
times_rotated = rotate_imm << 1;
for (i = 0; i < times_rotated; i++)
$display("Hello, World");
$display(""); // empty line as separate between changes to rotate_imm
end
assign out = in;
endmodule
