How Can I Resolve Plotting Error?

Hello, I attempted to plot two functions. Here a version of what I tried to plot with simplified equations, since I don't think the equations are the issue here, just the coding jargon. All variables are predefined, with x_2 being an array of 99 values and temp being a constant:

clc;    %clear the console
clear all;  %clear all the variables
%%defitions
temp=2000;     
x_2=0.01:0.01:0.99;         
Gm_s=zeros(99);
Gm_l=zeros(99);

for i=1:99
    x_1=1-x_2(i);
    Ll=11760*temp*(x_1-x_2(i));
    Ls=8366+*temp(x_1-x_2(i));
    Gm_l(i)=(x_2(i)*Ll)+(x_1*Ll);
    Gm_s(i)=(x_2(i)*Ls)+(x_1*Ls);
end

plot(x_2,Gm_s,'DisplayName','Solid G')
hold on
plot(x_2,Gm_l,'DisplayName','Liquid G')
legend
hold off

My resultant graph looks like this. I had attempted without the legend function and had still gotten a similar result.

I want a graph that shows how Gm_l and Gm_s vary with x_2. How do I fix this problem?

clc;    %clear the console
clear all;  %clear all the variables
%%defitions
temp=2000;     
x_2=0.01:0.01:0.99;   
% Get the correct size for Gm_s Gm_l
Gm_s=zeros(size(x_2));
Gm_l=zeros(size(x_2));
for i=1:99
    x_1=1-x_2(i);
    Ll=11760*temp*(x_1-x_2(i));
    % Ls=8366+*temp(x_1-x_2(i));   % error here
    Ls=8366*temp*(x_1-x_2(i));
    Gm_l(i)=(x_2(i)*Ll)+(x_1*Ll);
    Gm_s(i)=(x_2(i)*Ls)+(x_1*Ls);
end
