Filling the area between two open ended curves

I want to fill the area between the curves as shown in the attached picture. I tried fliplr and flipud, it does not work. Also I tried the below function and it still gives me a wrong output.

function val=area_col(fname)
p=load(fname);
x=p(:,1);
y1=p(:,2);
y2=p(:,3);
fx=[x x(end:0:1)];
fy=[y1 y2(end:0:1)];
figure
hold on
plot(x,y1);
plot(x,y2);
fill_color=[.929 .694 .125];
fh=fill(fx,fy,fill_color);
hold off

Thank you very much for any support.

Thank you Darova, I tried and yieled the below graph, which actually it not what I want. I attached my data as well.

p=load('L_D copy.txt');

x=p(:,1);

y1=p(:,2);

y2=p(:,3);

fx=[x x(end:-1:1)];

fy=[y1 y2(end:-1:1)];

figure

hold on

plot(x,y1);

plot(x,y2);

fill_color=[.929 .694 .125];

fh=fill(fx,fy,fill_color);

hold off

Thank you very much in advance!

Try this:

p = load('L_D copy.txt');
x  = p(:,1);
y1 = p(:,2);
y2 = p(:,3);

figure
plot(x, y1,    x, y2)
hold on
fill_color=[.929 .694 .125];
patch([x; flipud(x)], [y1; flipud(y2)], fill_color)
hold off
