Why is my plot not showing?

I'm trying to plot some Fourier Exponential Series but everytime I run my script nothing is comming out.

This is my script, any ideas on what am I doing wrong?

clc; close all; clear all;
%%Periodic Signal: Parameters
A = 6;
T = 10;
Co = 0;
%%Obtain distance between times
Wo = 2 * pi / T;
t0 = T;
tf = 1.5 * T;
dt = tf /500;
t = 0 : tf : dt;
%%Square wave aproximation
Vt = Co * ones (size (t));
for n = 0 : 1 : 100
    Cn = (4 * A / n*pi) * sin(n * pi/2);
    Vt = Vt + Cn * exp(1j * n * Wo * t);
    plot(Vt, t),...
        xlabel('Time (s)'),ylabel('V(t)'),...
        title('Aproximation '),grid on,...
        hold on;
end

 %rue
    clc; close all; clear all;
%%Periodic Signal: Parameters
A = 6;
T = 10;
Co = 0;
%%Obtain distance between times
Wo = 2 * pi / T;
t0 = T;
tf = 1.5 * T;
dt = tf /500;
t = 0 : dt : tf;  % time step is larger than vector, dt used as time step 
%%Square wave aproximation
Vt = Co * ones (size (t));
for n = 1 : 1 : length(t)
    Cn = (4 * A / n*pi) * sin(n * pi/2);
    Vt(n) = Vt(n) + Cn * exp(1j * n * Wo*t(n));
    plot(t(1:n),Vt(1:n)),...
        xlabel('Time (s)'),ylabel('V(t)'),...
        title('Aproximation '),grid on,...
        hold on;
end

Use for loop indexing for Velocity, Vt and time t

That was very helpful, thank you.
